The LH–RH chart can be very useful in micromotion analysis, as discussed in a later section. The chart can show inefficient physical arrangements as well as inefficient uses of the two hands. 4 gives an example of a LH–RH chart for the process of assembling caramel apples. We can see that the left hand is not very productive in this process, and we could then explore ways to improve the process. Process Planning and Job Design 57 MAN–MACHINE SYSTEMS We have seen the use of the activity chart to illustrate the activities of man– machine systems.

Similarly, the outside shape of the building needs to be kept simple to control construction costs. PRODUCT LAYOUT ANALYSIS We turn now to the problem of grouping tasks together into work stations in order to produce a balanced assembly line. Assume, for example, that a company desires to produce 200 units of a certain product per week (in a 40-hour week). As shown below, it has collected data on task times and sequencing requirements. The sequencing requirements are given by specifying what other tasks each task must follow.

The constraint of having just one shovel prevents us from reaching this optimum ratio of trucks to shovels exactly. If we allowed ourselves to consider a larger number of shovels, we could come much closer to this ratio, such as with 13 trucks and 3 shovels. However, this larger system might well work faster than we need, and we would have to pay for all the unnecessary equipment. In the current situation, then, we would consider having either 4 or 5 trucks in the system to come fairly close to the optimal ratio.
