CHAPTER 7
CAPACITY AND FACILITIES DESIGN
CHAPTER LEARNING OBJECTIVES
1. Discuss long-term capacity planning strategies. Capacity planning is the process of establishing the overall level of productive resources for a firm. It involves long-term strategic activities, such as the acquisition of new facilities, technologies, or businesses, that take a year or more to complete.
Capacity expansion can lead demand, lag behind demand, or meet average demand. The best operating level for a facility often includes a capacity cushion for unexpected occurrences. The tendency of high levels of output to cost less per unit is known as economies of scale. This normally holds true up to a certain level of output, at which point diseconomies of scale can take over.
2. Indicate the benefits of effective facility layout. Modern production and service facilities involve a complex mix of functions and operations. Facility decisions are an important part of operations strategy. An effective layout reflects a firm’s competitive priorities and enables the firm to reach its strategic objectives.
3. Explain the general characteristics of process, product, and fixed-position facility layouts. Batch production, which emphasizes flexibility, is most often organized into a process layout (grouping similar activities together into work centres according to the process or function they perform), whereas mass production uses a product layout (arranging activities in a line according to the sequence of operations that are needed to assemble a particular product) for maximum efficiency. Because of their size and scope, projects tend to use fixed-position layouts.
4. Use block diagramming and relationship diagramming to design process layouts. When quantitative data are available, a block diagram is used to create a schematic layout that includes space requirements. The objective of block diagramming is to assign each department to a block on a grid so that non-adjacent loads are minimized. In situations for which quantitative data are difficult to obtain or do not adequately address the layout problem, the quantitative data can be replaced with subjective input from analysts or managers using relationship diagramming and Muther’s grid. The information from the grid can then be used to construct a relationship diagram that evaluates existing or proposed layouts.
5. Describe the general considerations for service layouts. Service layouts are concerned with the flow of customers through various processes or departments. Thus, they concentrate on the circulation of customer traffic through the facility. Service layouts may try to process customers through the system as quickly as possible or maximize customer exposure to products and services.
6. Design a simple product layout for efficiency (balance a basic assembly line). The cost of moving material is still a primary consideration in layout design. Today, as in the past, layout decisions are concerned with minimizing material flow. However, with reduced inventory levels, the emphasis has shifted from minimizing the number of loads moved to minimizing the distance they are moved. Instead of accumulating larger loads of material and moving them less often, machines are located closer together to allow the frequent movement of smaller loads. Planners who used to devote a considerable amount of time to designing the location of storage areas and the movement of material into and out of storage areas are now concerned with the rapid movement of material to and from the facility itself. The logistics of material transportation is discussed in Chapter 10, “Supply Chain Management Strategy and Design.”
7. Describe three types of hybrid layouts, including cellular layouts, flexible manufacturing systems, and mixed-model assembly lines. In the current manufacturing environment of new product introductions, rapidly changing technologies, and intense competition, the ability of a manufacturing system to adapt is essential. Thus, several hybrid layouts have emerged that combine flexibility and efficiency. Reductions in setup times have made mixed-model assembly lines feasible. The newest flexible manufacturing systems (FMSs) can process any item that fits the dimensions of the pallet on which it is transported. Manufacturing cells that resemble small assembly lines are designed to process families of items. Some companies are placing wheels and casters on their machines so that the cells can be adjusted as needed. Others are experimenting with modular conveyor systems that allow assembly lines to be rearranged while workers are on their lunch break.
