      A project is an enterprise consisting of several activities which are to be carried out in some specific order. The activities and the order in which they need to be carried out can be represented by a pert network. Two ...

    • Economic order quality when a discount is offered on cash purchases

      Classical Wilsonzs EOQ model assumes that the payments for goods are made at the time of delivery and therefore a sufficient portion of carrying cost is incurred due to money blocked in inventories. In many situations, ...

    • Economic order quantity when ordering costs are lot size dependent 

      Gupta, Omprakash K. (2010-03-23)
      Classical EOQ model assumes that the ordering cost A is constant and independent of lot size. This paper deals with the case when A depends on the lot size and increases at a decreasing rate. Firstly A is assumed to increase ...
