This paper addresses cooperative game theory based bi-objective inventory routing problem, where replenishment plans are assumed as a coalition structure. Particularly, a distribution system is a set of customers that may order a single product from unique wholesalers to satisfy their own demands. When the products are carried from one depot to cus...

An increase in the number of patients and death rates make Covid-19 a serious pandemic situation. This problem has effects on health security, economical security, social life, and many others. The long and unreliable diagnosis process of the Covid-19 makes the disease spread even faster. Therefore, fast and efficient diagnosis is significant for d...

Airline alliances provide more flights, include different destinations, and maximize revenues. In an alliance, collaborating airlines can offer tickets for an identical flight plan, unlike the traditional single airline approach. In particular, due to epidemic/pandemic events, such as COVID-19, the available customer demands become highly uncertain...
Chapter
In this chapter, the authors extend transportation situations under uncertainty by using grey numbers. Further, they try in this research building models for grey game problems on transportation situations proposing the ideas of grey solutions and their corresponding structures. They introduce cooperative grey games and grey solutions. They focus o...

Inventory routing problem combines inventory management and vehicle routing problem. As a real-life distribution system, the furniture roving parts manufacturing company has the 1-depot and 30-customers at 12 periods. The model information involves the demand level, the initial inventory level and maximum inventory level for each customer with the...

A system on which the information is partly known and partly unknown is called the grey information. In this paper, we extend classical transportation games by using grey information. We introduce cooperative grey games and focus on sharing equal surplus Solutions. In transportation situations, it may affect the optimal amount of goods and conseque...

Full-text available
The grey systems theory is a new methodology that focuses on the study of problems involving small samples and poor information. It deals with uncertain systems with partially known information through generating, excavating, and extracting useful information from what is available. So, systems’ operational behaviors and their laws of evolution can...

Stok yönetimi çalışmalarında birim zamanda ortalama toplam stok maliyetini ve depolanacak ürün miktarını belirlemek firmalar için önemli bir konudur. Ancak gerçek hayatta stok maliyeti parametreleri tam olarak bilinemeyebilir fakat belirli aralık olarak tahmin edilebilir. Ayrıca birden fazla firma ortak hedeflere sahip olan firmalar ile stok ve sip...
Article
In this paper, some set-valued solutions using grey payoffs, namely, the grey core, the grey dominance core, and the grey stable sets of cooperative grey games are introduced and studied. The findings of the study demonstrated the relations between the grey core, the grey dominance core, and stable sets of grey cooperative games. Moreover, we prese...
Article
Purpose – The purpose of this paper is to extend the results of Meca et al. (2004) depending on the grey information revealed by the individual firms. Design/methodology/approach – The authors introduce cooperative grey games and focus on sharing ordering cost rule (SOC-rule) to distribute the joint cost. Findings – In this study, the authors int...

The basis of the energy management constitutes the forecasting of the need for energy as much as accurate. In this study, a hybrid genetic algorithm-simulated annealing (GA-SA) algorithm based on linear regression has been developed and coded as software to forecast natural gas demand of Turkey. The linear models, which are constructed by using the...

Basically, uncertainty is present in almost every real-world situation, it is influencing and questioning our decisions. In this paper, we analyze transportation interval games corresponding to transportation interval situations. In those situations, it may affect the optimal amount of goods and consequently whether and how much of a product is tra...

Article
The Shapley value, one of the most common solution concepts of cooperative game theory is defined and axiomatically characterized in different game-theoretic models. Certainly, the Shapley value can be used in interesting sharing cost/reward problems in the Operations Research area such as connection, routing, scheduling, production and inventory s...

In this paper, we extend mountain situations by using interval calculus. We define the interval Bird allocation and show that this allocation is a special core element of the interval cost game corresponding to an interval mountain situation. We deal with the interval cost sharing problem by introducing the cooperative interval cost game. Further,...

Determining customer needs and ensuring customer satisfaction are very important and essential issues in educational services. The factors which cause this dissatisfaction must be determined and the necessary arrangements must be constructed to achieve these goals. In this study, the correct selection of quality factors and determination of priorit...

Shewhart control charts for statistical process control are important tools to examination abnormal changes in a process. Artificial Neural Networks and Bayesian pattern recognition systems are formed to identify patterns of abnormal changes in a process to identify changes that may occur over time, to keep a process under control and to take neces...

The basis for energy management is to estimate the demand for energy as accurately as possible and without error. There are many studies related to demand forecasting in the literature. In this study, the support vector machines and artificial neural networks models were used to estimate the natural gas demand of Turkey. The correct forecasting of...

Due to result of increasing competition in production enterprises, the prices have been determined by customers. So, the product costs must be improved at lack of quality costs except basic costs. Therefore, the enterprises will increase their profits and will sustain manufacturing and organizational processes. An input quality control is a prevent...
