The dairy industry has a special place in the global food industry. The specific characteristics of this chain, such as spoilable products and reversible waste, emphasize the need for attention to the dairy supply chain. In the meantime, the issue of byproducts in reducing waste, creating high added value, and reducing the corresponding environment...

Aggregate production planning (APP) is concerned with determining the optimum production and workforce levels for each period over the medium term planning horizon. It aims to set overall production levels for each product family to meet fluctuating demand in the near future. APP is one of the most critical areas of production planning systems. Aft...

The paper deals with the dairy valorization problem. A new stochastic model for optimizing dairy valorization model is proposed. It takes into account the multipurpose and batch characteristics of dairies and employs the time resource distribution over the processing nodes and products.

This paper develops inventory models of a vendor-buyer supply chain with imperfect products and shortages based on Rad et al. [M.A. Rad, F. Khoshalhan, C. H. Glock, Optimizing inventory and sales decisions in a two-stage supply chain with imperfect production and backorders. Comput. Ind. Eng. 74 (2014) 219-227] and assumes that both the selling pri...

Research was conducted on a group of Iranian organizations to study the state of adoption and the conditions of potential influential factors. MCDM methods, TOPSIS and Entropy, were applied to uncover the real determinants of e-HRM configurations. Furthermore, the images of organizations situated in different levels of adoption provided an empirica...

We investigate a one-buyer-multi-vendor coordination model with vendor selection problem in a centralized supply chain. In the proposed model, the buyer selects one or more vendors and orders an appropriate quantity. The quantity discount mechanism is used by all vendors with the aim of coordinating the supply chain. We formulate the problem as a m...

Purpose: The aims of this article are to develop an integrated production-inventory-marketing model for a two-stage supply chain, and to study the effect of coordination on the performance of the system. The demand rate of the end customer is assumed to be sensitive to the selling price. The inventory models are developed, and then optimal values o...

Supply chain members cannot act independently and they need to act as a part of a unified system and coordinated with other members. Therefore, a coordination mechanism may be necessary to motivate members to achieve coordination. In this paper, the coordination problem is studied in a two-level supply chain consisting of a supplier and a retailer...

In the recent decade, studying the economic order quantity (EOQ) models with imperfect quality has appealed to many researchers. Only few papers are published discussing EOQ models with imperfect items in a supply chain. In this paper, a two-echelon decentralized supply chain consisting of a manufacture and a supplier that both face just in time (J...

This paper studies the issue of channel coordination for a decentralized supply chain consisting of one vendor and one buyer in multi-period setting. Considering the allowance of the backorder at the buyer side distinguishes this work in the literature. The credit option contract as an incentive scheme is pursued to encourage the buyer to participa...

Meeting Scheduling Problem (MSP) arranges meetings between a number of participants. Reaching consensus in arranging a meeting is very diffuclt and time-consuming when the number of participants is large. One efficient approach for overcoming this problem is the use of multi-agent systems. In a multi-agent system, agents are deciding on behalf of t...

Location-based advertising (LBA) opens up new frontiers for marketers to place their advertisements in front of consumers. LBA is a new form of marketing communication that uses location-tracking technology in mobile networks to target consumers with location-specific advertising on their cell phones. It provides more targeted communication and int...

The main idea of this research is to devise the smart module to pick the best supplier bid(s) automatically. The hybrid model is composed of three useful tools: fuzzy logic, AHP, and QFD. The approach has been carefully implemented and verified via a real-world case study in a medium-to-large industry manufacturing vehicle tires and other rubber pr...

This paper developed integrated production–inventory-marketing models for a two-stage supply chain consisting of one vendor and one buyer. The aim of the paper was to decrease the inconsistency between theory and practice of inventory management by relaxing some unrealistic assumptions such as constant demand and fully perfect items that make the m...

In recent years, studying the economic order quantity (EOQ) models with imperfect quality has appealed to many researchers. Only few papers are published discussing EOQ models with imperfect items in a supply chain. In this paper, a decentralized two-echelon supply chain facing an inventory problem is considered and a game theoretic approach is pro...

In this paper, an inventory model for two-stage supply chain is investigated. A supply chain with single vendor and single buyer is considered. We assume that shortage as a backorder is allowed for the buyer and the vendor makes the production set up every time the buyer places an order and supplies on a lot for lot basis. With these assumptions, t...

This article investigates integrated production-inventory models with backorder. A single supplier and a single buyer are considered and shortage as backorder is allowed for the buyer. The proposed models determine optimal order quantity, optimal backorder quantity and optimal number of deliveries on the joint total cost for both buyer and supplier...

Nowadays, it is increasingly acknowledged that the information delivered through the use of ICT has become a core aspect of international socio-economic development. So our society is forming anew as an Information society. The proposed i-society value chain assessment model in this paper includes all supportive and primary building blocks for crea...

Reaching to an agreement in meeting arrangements has always been a hard and cumbersome task, especially when there are many participants. An efficient approach to this problem is multi-agent systems. When we are designing a multi-agent system where agents are making decisions behalf of users we face another problem. How agents can model users' pref...

This paper investigates an integrated inventory model with fuzzy order quantity and fuzzy shortage quantity. We express order quantity and shortage quantity as the normal triangular fuzzy numbers and then we will find the membership function of fuzzy cost and its centroid. We find that the estimated value of the total cost in the fuzzy sense is hig...

In order for an organization to fully realize its knowledge management related objectives, it requires a knowledge management system to support it. The organization faces various challenges regarding this system, including whether or not to adopt it, as well as in case of the former, whether users would accept to work with it. Therefore, adoption o...
