Less Than

Consider the Competition

Location also important for service operations.

Minimizing Emergency REsponse Times

Location of emergency units, such as fire and ambulance, is determined by minimizing response time, providing minimum coverage, and operating from a mobile location. Response is important when time is a critical factor. Objective is to maximum response time is minimized. Minimum coverage implies that ALL customers have a minimum level of coverage.

Leverage

Making a workforce more productive through the use of better tools.

Government Incentives

Many state and local governments may offer significant reduction in property taxes, offer low-interest loans, provide free training to workers, and subsidize wages for a period of time, help slice through red tape, buy parcels of land by using power of eminent domain -- aggressive efforts to attract new businesses

Utilities

May have both fixed and variable components. Some are variable - power to run a drill press - others not directly to product such as energy to heat building Fixed is in overhead, variable shown seperate

Capacity

Measure of an organization's ability to sustainably provide customers with the demanded services or goods in the amount requested and in timely manner, given current resources. Maximum sustainable rate of production.

Capacity Estimation

Necessary prerequisite to capacity planning. Knowledge of existing limits. Capacity function of management ingenuity, influenced by good planning, good operating procedures, effective maintenance programs, and other management decisions.

The Acme Manufacturing Company is operating at a maximum rate of production and meeting the demand of its customer base. Acme is

OPERATING AT CAPACITY

Projects Process

One-of-a-kind operations, batch size is one Ex large construction jobs, new computer software/hardware In a sense, entire cost is variable - fixed costs in the form of overhead spread over multiple projects Project-oriented operation is very flexible, allowing extensive customization of the finished product - common in service operations

Flexible Manufacturing System (FMS)

PROCESS OPTION -- LOW COST PRODUCTS Similar to Manufacturing cells; difference has more automation, robots and computer control - tends to operate without people capture new markets by accumulating production requirements from several low-volume products. Higher-volume operations- a set of machines in one layout to produce all the different products. The products, must be similar enough to have the same or a similar sequence of operations, and the machines must be flexible enough to handle the differences.

A -Select- layout is characterized by high consumer demand for similar goods that have few variations.

PRODCUT ORIENTED

Which of the following involves a firm having one manufacturing location to produce one product and shipping the product around the country or world?

Referred to as line flow processes such as continuous flow. Does not ID w/ individual units - product flow is mixed and flows as continuous stream. Ex oil refining, processing checks Relatively high fixed costs and relatively low variable costs.

A -Select- is used when customer convenience and access are important, or when outbound transportation costs are very high.

Regional facility strategy.

Manufacturing Cells

Rely on group technology to build a family of parts w/ similar design and processing characteristics. Classify parts based on size, shape, use, type of material, and method of production. Reduce material-handling costs, increase machine utilization, and shorten production lead times. Since processing is similar, less time is required to change from one product within family to next.

IKEA Canton is thinking of adding another shift to the work day at the store. This would be an example of what type of constraint?

Review the process, resource, and demand constraints and find the next bottleneck.

John realizes that IKEA's capacity planning deals with its status as a -Select-

Service

Jennifer wants to review the several locations for the new gas station logically. Jennifer should prepare a _____________ analysis.

Side-by-side cost

Continuous Flow and Assembly Line Similarities and Differences

Similarities* Dedicated facilities producing large volumes with little difference in products ** Product layout** equipment process should be around the product so material-handling and transport costs not excessive Differences* Continuous flow - often commodity - emphasis on measuring inputs & compare to outputs Assembly-line - allows some variations - options usually selected from list - minor adjusted needed to make variation can be done by worker; technology allows to be more flexible

System Capacity

The ability of an overall organization to produce a sufficient number of goods and services to meet the demands of customers, considering both its strongest and weakest production points

Effective Capacity

The capacity a firm can expect to achieve, given its product mix, equipment changeovers, and scheduled downtime of the production schedule. (Design capacity minus projected issues such as breakdowns/maintenance, etc)

If the furniture department has 60 customers visit each hour and the lighting department has 30 customers visit each hour, what is the problem facing IKEA?

Capacity in the IKEA store could be measured by which of the following?

The number of orders placed in the appliance department.

Facility location

The placement of a facility with regards to a company's customers, suppliers, and other facilities with which the company interacts. Factors: costs to acquire land, building, as well as costs for labor, taxes, and utilities and operating costs. Convenience to customers - access to banking, education, and other activities.

Location Analysis

The process of evaluating whether a general location meets the requirements of being both possible and practical as defined on the basis of technical and functional components. * Coordinate plane

Step 3: Subordinate everything else to the above decision.

* Communicate decision to every dept in organization. Ensure workers and supervisors understand why. * All organization's decision must be aligned, or it will create dissatisfied workers, excess inventory and unhappy customers. * once system has achieved throughput on a stable basis, it is time to consider adding more capacity.

Step 4: Elevate the system's constraint.

* Determine how to increase bottleneck's capacity by adding another shift or outsourcing work. Or adding another machine or outsourcing work. Often requires financial analysis to determine which option will have best return on investment. *Ex adding half-shift of part-time workers to a department in evening will increase capastiy.

Step 2: Exploit the system's constraint.

* Ensure bottleneck dept is at 100% capacity utilization and efficiency. * Common ways of achieving high capacity utilization include training, equipment maintenance, and cross-training so that the bottleneck is never shut down for breaks. * Increase output by cross-training, implementing staggered lunch times, or increase work day to 9 hours.

Step 5: If a constraint has been broken, go back to Step 1. Do not allow inertia to cause a system's constraint.

* Once more capacity has been added, it is no longer the bottleneck. Are there any other constraints which may prevent this system from achieving throughput. Yes - next bottleneck would be Dept D which can only produce 68.5 units per day. Step 5 reminds us to keep seeking ways to improve our processes.

When Proximity Matters

* customers that use a service facility in person, being close to customers is very important Ex retail * transportation costs are important for warehousing and distribution, but response time - time elapsed between request and delivery may be more important.

Five-Step Thinking Process

1) ID system contraints. 2) Exploit the system's constraint. 3) Subordinate everything to the above decision. 4) Elevate the system's constraint. 5) If a constraint has been broken, go back to step 1. Don not allow inertia to cause a system's constraint.

A factory which makes Nike sneakers is most likely to use a process layout.

FALSE - Would use Product layout.

Review the Beck Manufacturing example and your results from the last exercise to reconfirm Step 1 of the Theory of Constraints process. Remember the conditions: There are two possible processes in production. 50% of steering gears go through process A, and 50% of steering gears go through process B. Total customer demand is 200 steering gears per hour. Al is able to buy all the parts he needs for production. The factory operates 8 hours per day. He has found that Sub-Assembly Dept. A can produce 110 sub-assemblies per hour, Sub-Assembly Dept. B can produce 120 sub-assemblies per hour, Final Assembly Dept. can produce 200 products per hour, and Testing Dept. can test 210 steering gears per hour. For Step 2, Beck Manufacturing should ensure that Sub-Assembly departments A and B each produce 110 units per hour.

False Correct. Final Assembly is the bottleneck. It is unable to assembly 220 steering gears per hour. If the Sub-Assembly departments produce more than Final Assembly can process, it will simply lead to an ever-growing pile of work-in-process inventory.

True or False The evaluation of quantitative factors is always more important than of qualitative factors when making service location decisions.

False Correct! Even though qualitative factors do not usually have measurable, direct effects, they do need to be carefully considered and integrated with quantitative factors when making service location decisions.

True or False Qualitative factors, including potential costs and revenues, must be organized for each site in a way that allows them to be easily compared when making service location decisions.

False Correct! Potential costs and revenues are considered quantitative costs. Potential costs and revenues, however, must be organized for each site in a way that allows them to be easily compared when making service location decisions.

True or False Qualitative factors do not usually have measurable, direct effects, so they do not need to be compared when evaluating location alternatives.

False Correct! Qualitative factors do not usually have measurable direct effects, but they are important to integrate with quantitative factors when making location decisions.

True or false? A product-oriented layout is characterized by demand for a variety of products that have different production requirements.

False Correct. A process-oriented layout, rather than product-oriented, is characterized by the production of many different products with the same equipment and low volume of any individual product. Each product has different production requirements that place different demands on the equipment.

A large regional bank is considering two locations for its new call center. One, a mid-sized city, features inexpensive real estate and low taxes but rates low in national "quality of life" surveys. The other, a large metropolitan area, features a highly educated, sophisticated workforce and easy access to a large airport but its cost of living rates are in the top 5%, nationally. True or false? A responsible site selection process will focus on cost factors but may ignore less tangible issues like quality of life and access to transportation.

False Correct. Both quantitative (such as cost) and qualitative (such as access to transportation) factors should be analyzed because, when integrated, they can influence service location decisions.

True or false? Economy of scale requires flexibility within the organization and suggests building volume to cover fixed costs by producing a variety of products on the same equipment.

False Correct. Economy of scope requires flexibility within the organization to produce a variety of products.

Once effective capacity is determined, it does not change unless new capacity is added.

False Correct. In general, capacity is not fixed. Effective capacity is a realistic estimate of what a system could produce, given planned downtime, which is influenced by the number of employees on vacation, new hires who are learning their jobs, and machines undergoing annual and planned maintenance.

Jacqui Vozzotti is an up-and-coming fashion designer from Kenya. Her designs received rave reviews at fashion shows across Europe and Asia, and she and her work have been featured in many articles in the fashion press. Her management team advises her that the time is right to open an exclusive retail boutique to highlight her designs. But, her investor-partner balks when she insists on locating the facility on "Fashion Row" in Rome, a multi-square block area where premiere designers present their wares to well-heeled shoppers. He insists that rent is far too expensive, as much as 10 times as high as a suburban storefront. Jacqui stands firm, maintaining that, to be successful, she must be located alongside her competitors. True or false. Jacqui's partner is right. Competitors' locations should not be an important consideration when choosing a location.

False Correct. Much like auto dealers or fast food restaurants, fashion boutiques can expect the location of their competitors to influence their own service location decisions because they can have a positive or negative impact on sales.

Al Beck, president of Beck Manufacturing, has decided to implement the Theory of Constraints 5-step thinking process in his manufacturing facility, which produces steering gears for auto manufacturers. The operation produces large numbers of nearly identical products. The image above shows the manufacturing process for gears. As shown in the diagram, there are two possible processes in production. 50% of steering gears go through process A, and 50% of steering gears go through process B. Total customer demand is 200 steering gears per hour. Al is able to buy all the parts he needs for production. The factory operates 8 hours per day. He has found that Sub-Assembly Dept. A can produce 110 sub-assemblies per hour, Sub-Assembly Dept. B can produce 120 sub-assemblies per hour, Final Assembly Dept. can produce 200 products per hour, and Testing Dept. can test 210 steering gears per hour. Apply Step 1 of the TOC 5-step thinking process. In the current process, the bottleneck is Hint, displayed below-Select-. A For Beck Manufacturing, the effective capacity of the system is Hint, displayed below-Select-.

Final Assembly Dept / 200 steering gears per hour

Capacity Decisions for Service Operations.

General rule is that services are produced and consumed simultaneously which means they must: 1) build enough capacity to meet maximum demand 2) manage demand so that people will use the services at off-peak times 3) choose not to satisfy all the demands Costs of decision: 1) Too large of capacity means significant portion of capacity is used infrequently. 2) High degree of producer-consumer interaction - creates uncertainty of processing time 3) Many services are not transported to customer, so the customer must come to the service delivery system.

Applying TOC in Capacity Planning

Step 1: ID the Constraint

Which type of operation would most likely benefit by using a regional facility strategy?

Subway franchise

Theory of Constraints (TOC)

Systems management philosophy that states that every organization is hindered by constraints that come from its internal policies. Continuous process. Creating optimal throughput.

Girardi's, a happy hour wine bar, has outgrown its current location in a busy pedestrian mall in a bustling Northeastern city. Girardi's has built its reputation around its large patio seating area, where young professionals who work in the hip startups that surround the location, often gather with friends to blow off steam after work. As it reviews options in anticipation of a move, it finds that locations in suburban malls are much less expensive per square foot than locations that match its current ambiance and accessibility to its clientele. True or false? In choosing its next location, Girardi's should consider the value its current customers place on its location and accessibility, versus the savings it would incur in a much less expensive location.

TRUE

True or false? Although qualitative factors lack measurable, direct effects, they can be included in service location decisions if managers focus on the most relevant factors and give each factor a weight.

TRUE

True or false? Both continuous flow and assembly line processes use dedicated facilities to produce large volumes of goods with few, if any, product differences.

TRUE
