Coleman distributes 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 companys current warehouse operation, warehouse clerks dispatch order-picking personnel to fill each order and the goods moved to the warehouse shipping area. Due to the high labor cost and the relatively low productivity of hand order-picking, the company 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 shipping area. As R. C. Colemans director of material management, you have been named the project manager in charge of the automated warehouse system. After consulting with members of the engineering staff and warehouse management personnel, you have compiled a list of activities associated with the project, along with various time and cost estimates.
