Decision making plays an important role in economics, psychology, philosophy, mathematics, statistics and many other fields. In each field, decision making consists of identifying the values, uncertainties and other issues that define the decision. In any field, the nature of the decisions is affected by environmental characteristics. In this paper, we are considered the production planning pro...

The German Armed Forces provide an operation contingent to support the North Atlantic Treaty Organization (NATO) Response Force (NRF). To fulfill a mission, NRF operates number of technical systems, mostly vehicles. Each system is composed several parts which might fail over time, and it can only be used again in mission if all broken are replaced. For short deployments (e.g., one month), troop...

Constrained multi-item inventory system with variable demands are considered. The demand rates of five selected - Cowbell, Milo, SMA, Cerelac and Golden Morn were modeled as Weibull, Normal Lognormal probability distributions respectively the aid chi-squared multinomial goodness-of-fit test. respective estimated location parameters: 491.55, 536.92, 10.5, 2.1926 5.3103 used basis probabilistic m...

  This paper aims to evaluate inventory cost of a Two-echelon serial supply chain system under vendor managed inventory program with stochastic demand, and examine the effect of environmental factors on the cost of overall system. For this purpose, we consider a two-echelon serial supply chain with a manufacturer and a retailer. Under Vendor managed inventory program, the decision on inventory ...

In this paper, we consider the inventory robust constraint control problem with an uncertain demand. The considered system deals with a non-linear discrete-time stochastic model of a special structure. The robust control designing, consisting in the inventory product level minimization by the corresponding adjustment of the production rate, is shown to be converted into certain attractive ellip...

We study the inventory control problem of a retailer working under stochastic demand and stochastic limited supply. We assume that the unfilled part of the retailer's order is fully backordered at the supplier and replenished with certainty in the following period. As it may not always be optimal for the retailer to replenish the backordered supply, we also consider the setting in which the ret...
