Abstract:

Managing inventory-related risks is crucial for companies dealing with fixed lifetime inventories. Previous researches have focused on the study of inventory management and risk management. However, there are no adequate study in the literature that combines these two critical aspects in the mamagement of fixed liftetime inventories. We developed a stochastic optimization problem and minimized the expected total costs. The aim of the study is to examine decisions as regards when to place order or not for the probabilistic fixed lifetime inventory model with expected insurance costs. We compute

Abstract:

Along with growing interest in environmental concerns these days, significant academic efforts have been exerted to incorporate sustainability issues into the existing inventory models except for fixed-review interval (i.e., order-up-to models). In this study, we develop an order-up-to model considering environment-related costs and investigate the value of this new policy over the naïve one. Results of an extensive simulation study reveal that sustainability consideration reduces the total costs and that its value is higher when the mean demand is higher, when demand is more variable, when th

AbstractThe fixed order quantity model of inventory management system is used in the deterministic part. Several elements of inventory cost, such as ordering cost, transportation and storing costs, frozen capital cost, as well as extra rebates, are taken into account in the model. Then the fuzzy optimization problem for the total cost function is formulated within the space of Ordered Fuzzy Numbers when all variables of the model are fuzzy. After the choice of a particular defuzzification functional an appropriate theorem is formulated which gives the solution of the problem.

Abstract:

In the classical economic order quantity (EOQ) inventory model, it was assumed that the retailer must pay for the received items immediately. However, in practice, the supplier not only allows retailer to settle the account after a certain fixed period but also may offer a cash discount to encourage the retailer to pay for his purchases as soon as possible. On the other hand, it is common practice in most inventory systems to hold excess stocks in a rented warehouse whenever the storage capacity of the owned warehouse is insufficient. Therefore, the purpose of this paper is to establish an EOQ

The purpose of this paper is to identify the determinants and indicate their impact on the company’s cash holdings in the wholesale industry in ten Balkan countries. Effective cash holdings management is key to any company’s healthy and smooth business operation, so comprehending and analyzing the relationship between the company’s internal determinants and cash holdings is vital. The sample used for this work included 106 companies, whose operations were studied over a four-year period (2014–2017), using the panel data model with fixed effects. The obtained results showed that three of the fi

Abstract:

Corporate social responsibility (CSR) has received much of the attention in supply chain management, in particular the pricing decisions. Most existing models that enable CSR integration into pricing decisions in a supply chain context assume deterministic demand and focus on a single distribution channel. Despite the fact that dual-channel supply chain (DCSC) has received popularity, most pricing decisions models in DCSC assume fixed and deterministic market share distribution between channels, and no demand leakages (cannibalization). This paper addresses these gaps by proposing a CSR enable

IntroductionFibromyalgia is associated with chronic widespread pain and disturbed sleep. Multidisciplinary, multimodal management often includes pharmacotherapy; however, current drugs used to treat fibromyalgia provide meaningful benefit to only 30–60% of treated individuals. Combining two or more different drugs is common in clinical practice with the expectation of better efficacy, tolerability or both; however, further research is needed to identify which combinations actually provide added benefit. Thus, we are planning a clinical trial to evaluate melatonin (MLT)–pregabalin (PGB) combina

Abstract:

Simulation-optimization inventory models are widely used in inventory management studies, including for perishable good. A good inventory management is required to save inventory cost. We use simulation approach to take into consideration of uncertain demand and lead time to obtain a better result of optimal order quantity that minimizes inventory cost. Simulation result shows that simulation-optimization models generates lower total inventory cost. The simulation provides information of objectives in inventory management: (1) how much to order and (2) when to order with minimum cost which giv

The optimal inventory quantity model with continuous demand is developed in this study. Controlling inventory is generally a key component of a successful business operation for any company that purchases and resells goods. For this reason, we create a mathematical inventory model that includes fixed transportation costs, decreasing holding costs, and shortage costs. The buyer's economic order quantity and the lowest possible total inventory cost are obtained. And also, we focus on the manufacturer - buyer inventory cost, which makes more profit. This model shows that determination of saving p

By considering a specific type of perishable goods this experimental investigation has been done based on linear decay and exponential decay.
