This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...

production, reproduction, management and economic parameters resulted from recordings of 5 flocks comprised of 720 heads of native goats during annual cycle of reproduction in transhumance, village and farming systems were employed to determine the performance of traits, cost-profit analysis as well as breeding objective. the overall mean for number of salable kid per goat in transhumance, vill...

In this research, the optimal pricing decisions for two complementary products in a two-echelon supply chain under two scenarios are studied. The proposed supply chain in each echelon includes one retailer and two manufacturers and the same complementary products are produced. In the first scenario, we assume the unit manufacturing costs of the complementary products in each echelon are the sam...

It is well-known how to use maximum flow to decide when a flow problem with demands, lower bounds, and upper bounds is infeasible. Less well-known is how to compute a flow that is least infeasible. This paper considers many possible ways to define “least infeasible” and shows how to compute optimal flows for each definition. For each definition it also gives a dual characterization in terms of ...

The relationship between the quality of finishing works, costs, market value, and profit, is presented and explained for residential buildings. The results show that the higher quality of finishing works increases profit for investors. As the maximum market price is limited, there is a limit when the investment in finishing work is no longer cost-effective as, after increase in costs, the marke...

a r t i c l e i n f o This paper develops an economic manufacturing quantity (EMQ) model with deterioration and exponential demand in a production system over a finite time horizon under the effect of inflation and time value of money. The production rate is a dynamic variable (varying with time) in a production system. Due to a long run process, the machinery system is converted from in-contro...

We present parallel algorithms for the PROFIT/COST problem with time complexity O(log n) using O(m + n) processors. The design of these algorithms employ both the derandomization technique and the pipeline technique. They can be used to partition the vertices of a graph into two sets such that the number of edges incident with vertices in both sets is at least half of the total number of edges ...
