T/F: In the context of simulation, random numbers are numbers that are uniformly distributed between 0 and 9.
False
a binding constraint is one for which the Cell Value is greater than the right-hand side of the value of the constraint
False
decision variables in an optimisation model are "known" values
False
simple bounds contain the value of multiple variables
False
which of the following best defines Monte Carlo simulation? - it's a tool for building models that characterise relationships among a dependent variable and 1 or more independent variables - it's a collection of techniques that seeks to group or segment a collection of objects into subsets - it's the process of selecting values of decision variables that minimises or maximises some quantity of interest - it's the process of generating random values for uncertain inputs in a model and computing the output variables o interest
It's the process of generating random values for uncertain inputs in a model and computing the output variables of interest
T/F: A value randomly generated from a specified probability distribution is called a random variate.
True
T/F: Risk analysis seeks to examine the impact of uncertain inputs on various outputs.
True
T/F: Uniform or triangular distributions are used in the absence of data.
True
T/F: a constraint function is a function of the decision variables in the problem
True
T/F: any solution that satisfies all constraints of a problem is called a feasible solution
True
T/F: as Monte Carlo simulation is essentially statistical sampling, the larger the number of trials used, the more precise the results.
True
constraints are limitations, requirements, or other restrictions that are imposed on any solution, either from practical of technological considerations or by management policy
True
T/F: in predictive modelling, verification refers to hw well a model represents reality
false
problem statements such as production must be sufficient to meet promised customer orders would be categorised as a ______ constraint
requirements
T/F: Requirement involve the specifications of minimum levels of performance
true
balance constrains essentially state that input = output and ensure that the flow of material or money is accounted for at locations or between time periods
true
infeasible problems can occur when the demand requirement is higher than the available capacity
true
proportional relationships are often found in problems involving mixtures or blends of materials or strategies
true
there are 3 types of optimisation models: linear, integer, and nonlinear
true
