R. C/ Coleman distribute a variety of food products that are sold through grocery store and supermarket outlets. The company receives orders directly from the individual outlets, with a typical order requesting the delivery of several cases of anywhere from 20 to 50 different products. Under the company’s current warehouse operation, warehouse clerks dispatch order-picking personnel to fill each order and have the goods moved to the warehouse shipping area. Because of the high labour costs and relatively low productivity of hand order-picking, management has decided to automate the warehouse operation by installing a computer-controlled order-picking system, along with a conveyor system for moving goods from storage to the warehouse …show more content…
ii. Optimistic time (a) = the minimum activity time if everything progresses ideally. Most Probable time (m) = condition. iii. Pessimistic time (b) = the maximum activity time if significant delays are encountered Below table is the result for the uncertain activities time achieved.

To ensure that the project is progressing as planned, Mr Coleman is advised to utilize and incorporate the analysis with the concept of probability distribution; Project Scheduling with Uncertain Activity Times. Such situation, the understanding and utilization of Program Evaluation and Review Technique (PERT) and Program of Critical Path Method (CPM) has proven to be
