Many times it happens that units ordered are not of 100% good quality. A deterministic inventory model with imperfect quality is developed when the deterioration rate is Weibull distribution. Here it is assumed that holding cost is time dependent. The model has been framed to study the items whose deterioration rate increase with time under permissible delay in payments with imperfect quality. ...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
Jamal et al. [2000. Optimal payment time for a retailer under permitted delay of payment by the wholesaler. International Journal of Production Economics 66, 59–66] study a wholesaler–retailer supply chain where the retailer is given a permissible credit period to pay back the dues without paying any interest to the wholesaler. The problem is modeled as a cost minimization problem with two deci...
This paper develops a supply chain framework where payments take place with permissible delays. Unlike other studies, the is modelled as closed-loop system, in which returning products incorporated into classical models and full backorder permitted. Among most important research questions order amount of members to maximize Retailer delays profit chains. The study determines portion time interv...
The retailer (buyer) is usually allowed a permissible credit period to pay back the dues without paying any interest to the wholesaler (supplier). In this problem the retailer can pay the wholesaler either at the end of credit period or later incurring interest charges on the unpaid balance for the overdue period. This research develops a retailer's model for optimal cycle and payment times for...
A continuous production control inventory model for deteriorating items with variable demand rate is developed. Demand rate is the linear function of time. In this paper we have done all work in the environment of permissible delay of payments. A number of structural properties of the inventory system are studied analytically. We have discussed the minimum total system cost under the condition ...
This paper derives a production model for the lot-size inventory system with finite production rate, taking into consideration the effect of decay and the condition of permissible delay in payments, in which the restrictive assumption of a permissible delay is relaxed to that at the end of the credit period, the retailer will make a partial payment on total purchasing cost to the supplier and p...
