Exam 5: Process Configuration Strategies

It is not critical to be able to chart in total detail every step of the process.

_____ are defined as the final part of the means-end chain.

Simulation is not the best method available for designing good processes.

_____ will depend upon which work configurations are best suited for the expected volumes and varieties of products.

Work configurations are successfully used for training,testing,and analyzing.

The supply chain uses both synthetic and analytic processes.

The marketing approach for analytic products is similar to that of synthetic products.

The concepts of OPT were developed by Eliyahu Goldratt.

It is possible,but necessary to justify,using a flow shop configuration for large batch-type (lower-volume and higher-variety) products.

The approach to evaluating alternative work configurations can be modeled to provide more structure.To exemplify,a model is constructed to evaluate under what conditions the intermittent flow shop (IFS) will be selected in preference to the batch production of a job shop (JS).For the IFS,setup,takedown and changeover costs have to be amortized over the lot size that is run.The IFS produces N units at a cost of c dollars per unit with a fixed setup cost of S dollars.Compare that cost with the cost of setup for the job shop production process,S¢.The lot size is the same but the cost per unit,c¢ > a.What is the choice when the lot size is N = 200? b.What is the choice when the lot size is N = 400? c.The cost comparison is shown here with some hypothetical numbers for costs and a lot size of N = 100.The costs are illustrated below. IFS: (cN + S)/N = (3 × 100 + 500)/100 = $8.00 per unit made JS: (c¢N + S¢)/N = (4 × 100 + 300)/100 = $7.00 per unit made So,choose to use the job shop to make the 100 units. Next,assume that the lot size is 500 units.IFS: (cN + S)/N = (3 × 500 + 500)/500 = $4.00 per unit made JS: (c¢N + S¢)/N = (4 × 500 + 300)/500 = $4.60 per unit made So,choose the IFS. Now,assume that both setup costs are triple the original amount.

A flow shop that can be shut down and dismantled has the same high level of special-purpose equipment as a full-time dedicated flow shop.

The Hayes and Wheelwright matrix defines product life cycles in terms of increasing volume and decreasing variety.

Progressive assembly,which follows the instructions of how to build sequentially the subassemblies and final assemblies,is an example of the analytic function.

_____ is flexible machinery that can do many different kinds of jobs.

Process steps often require the use of science and technology.

_____,also known as the theory of constraints,is a production process scheduling system.

Demand is affected by the variety,price,and the quality of product.

_____ is run for an interval of time and then shut down until required again.

Contingency planning requires first addressing what might be done to avoid damage and disaster before identifying things that might happen.

The systems approach rarely uncovers relationships in one part of the production chain that affect relationships in other parts of the chain.
