An inventory problem for a deteriorating item having two separate warehouses is developed under time value of money, whereby one is an own warehouse (OW) of finite dimension(s) and the other is rented warehouse (RW) of infinite dimension(s). Deterioration rate of items in the two warehouses may be different, which is time dependent and deterioration is in the mean beta distribution form. In this study, shortages and complete backlogging have been considered as the other items, whereby the demand rate of items is linear with time in OW and the same is linear with price in case of RW. Also, the stocks of RW transported to OW in continuous release pattern.

This study considers the problem of a vendor which supplies an item to the buyer with imprecise partial backlogging rate of unsatisfied demand and non instantaneous deterioration rate considering variable holding cost, the effect of inflation and time value of money. The supplier’s lead time is a stochastic function of his managing cost. The extra costs incurred by the retailer due to the uncertain lead time in terms of shortage costs or lost sales costs should be owed by the supplier. A numerical example is cited to illustrate the results and its significant features. Finally, to study the effect of changes of demand parameters, deterioration, inflation and managing cost on supplier and the retailer’s profit, a sensitivity analysis is presented numerically.

Value Of Money

This research is a case study of two Ijarah Sukuk issuances in two countries. One issued by central bank of Bahrain and matured in 2014 and the other was issued by the Malaysian company TSH Resources Bhd and matured in 2017. By adopting library research and document analaysis, this research examines the terms and conditions of both cases based on what has been disclosed in the prospectuses. Accordingly, this study presents the impact of the Time Value of Money (TVM) in these cases and how it differentiates between genuine Ijarah Sukuk and a duplicate-bond Sukuk. The study revealed that there were some Shari’ah non-compliance issues in the implementation of Sukuk concept in both cases in a way it emulates conventional instruments featured as guaranteed-return instruments, which take into account TVM as an essential compenent in calculating its returns. However, such practice has a major effect on the genuineness of Sukuk, in terms of Shari’ah-compliance risk.

Value Of Money

This paper develops an infinite time-horizon deterministic economic order quantity (EOQ) inventory model with deterioration based on discounted cash flows (DCF) approach where demand rate is assumed to be non-linear over time. The effects of inflation and time-value of money are also taken into account under a trade-credit policy of type "?/T1 net T". The results are illustrated with a numerical example. Sensitivity analysis of the optimal solution with respect to the parameters of the system is carried out.
