The objective in traditional scheduling is usually time based. Minimizing the makespan, total flow times, total tardi costs, etc. are instances of these objectives. In manufacturing, processing each job entails a cost paying and price receiving. Thus, the objective should include some notion of managing the flow of cash. We have defined two new objectives: maximization of average and minimum av...

This article focuses on solving the order quantity allocation problem for retailers. It considers factors such as quality constraints, nonlinear discounts, and price-dependent demand. By formulating it a maximization problem, aims to find best combination of suppliers out infinite solutions maximize retailer’s profit. The main contribution this research is new mathematical model that can solve ...

We consider a monopolist’s profit-maximization problem when the demand for the product is created by the referrals between consumers who are connected over the social network. The monopolist decides the price of the product and the referral fee which is awarded to consumers whose referrals lead to sales of the product. It is known that the social network in the real world has the small world pr...

Cryptocurrencies have recently attracted considerable attention, resulting in research mainly on deep learning-based price prediction models to maximize profit. Two approaches been adopted. Studies adopting the first approach directly predict future cryptocurrency price. Long short-term memory (LSTM) and gated recurrent unit (GRU), which show high performance time-series data, are used for this...

In this paper we develop an economic order quantity model to investigate the optimal replenishment policies for instantaneous deteriorating items under inflation and trade credit. Demand rate is a linear function of selling price and decreases negative exponentially with time over a finite planning horizon. Shortages are allowed and partially backlogged. Under these conditions, we model the ret...

While profit maximization is one important objective in this decision domain, other objectives are important as well. This paper discusses multiple criteria and their respective objectives in construction bidding, and presents a bidding framework which recommends a pairwise comparison procedure to generate criterion weights and a linear transformation procedure to calculate relative scores for ...
