Optimal production and predictive maintenance decisions for deteriorated products under advance-cash-credit payments

In the 4th industrial revolution era, manufacturers tend to integrate predictive maintenance into production systems to maximize the lifespan of equipment and avoid costly disruptions. Using internet of things sensors and data analyses, predictive maintenance can significantly reduce the production downtime by detecting and predicting system problems before they become uncontrollable, resulting in a lower defective rate. Additionally, an advance-cash-credit (ACC) payment scheme is commonly applied in real-world business transactions to enhance cash flow flexibility among supply chain members. In this study, we developed a supplier–manufacturer chain, wherein a predictive-maintenance-adopting manufacturer received an ACC payment from a supplier, to demonstrate a supply chain management situation within the imperfect economic production quantity framework. The inventory system of the manufacturer was modeled as a cost minimization problem to determine the optimal replenishment cycle time and predictive maintenance effort for deteriorated products. The proposed model also adopted a discounted cash-flow analysis to consider the time value of the cost function, which was proven to be strictly convex in the replenishment time and predictive maintenance effort. Furthermore, a numerical and sensitivity analysis was conducted to illustrate the effectiveness of the proposed model and gain management insights.

The Controllable and Non- Controllable Hurdles and Pushers to Executing Green Supply Chain Management in the Lebanese Hospitality Sector- the Case of Tannoury

Purpose: This study aims at determining the hurdles and pushers of green supply chain management in the Lebanese hospitality sector. Theoretical framework: This study adopts institutional theory to understand environmentally friendly supply chain management in the Lebanese hospitality sector, its pushers, and hurdles. Certain factors and pushers may influence businesses in their business actions (Hirsch, 1975; Lai et al., 2006). Design/Methodology/Approach: This exploratory qualitative research utilizes the case study approach through a physical semi- structured interview with the owner of Tannoury restaurant. Findings: It is found that there are two main controllable pushers mainly management mindset and green purchasing, one controllable hurdle namely employee resistance, and four non- controllable hurdles namely obscurity of GSCM awareness, lack of environmental awareness, absence of governmetal support and the Lebanese economic crisis. Research, Practical & Social implications: The results of such a study might be of great for the concerned Lebanese ministries and bodies to mandate the required legislation regarding green supply chain management. Such a study might be of great value for some non-governmental organizations and environmental associations, who may have a clearer view of the current green supply chain management situation in Lebanon. Originality/Value: This study is original and contributes to the Lebanese context and to the supply chain industry as a whole in as there exists no studies that tackled GSCM in the Lebanese hospitality sector.

Analysis of Supply Chain Management Solutions in Commodity Distribution Enterprises

At the present stage, at the level of supply chain management in the development of commodity distribution enterprises, supply chain management enterprises are located in the dominant position and have great rights in the overall supply chain management approach. If the commodity distribution enterprise holds strong influence, it will definitely cause the deterioration of the relationship between the specific commodity distribution enterprise and the supplier, thus invariably endangering the mutual gains. The strategic development plan of supply chain management of commodity distribution enterprises will be scientifically studied in this paper, and the current situation of supply chain management of commodity distribution enterprises will be introduced in detail, and the strategic development plan of optimized management will be formulated for the existing deficiencies to promote the stronger development of commodity distribution enterprises in the future. In general, improving the supply chain management countermeasures of commodity distribution enterprises, ensuring that commodity distribution enterprises and suppliers become excellent partners from supply chain management, analyzing and improving the development of strategic suppliers, and improving the relationship management between commodity distribution enterprises and suppliers will be beneficial to the economic benefits of commodity distribution enterprises.

A Bibliometric Analysis of Supply Chain Management Research from the Perspective of Social Network

ABSTRACTThe research mainly aims at the hotspot of supply chain management from the perspective of a social network by drawing knowledge mapping and provides the visualization reference in this research field. Firstly, it collects the literature data of the core database of Web of Science from 2003 to 2018. Then it uses the literature co-occurrence method, knowledge mapping method, and content analysis method, and analyzes the current situation of supply chain management under the perspective of social network. It also applies Citespace software and bibliographic co-existing analysis system to analyze the literature cooperation network and topic in this field. Results showed that there are three important research angles, including the analysis of supply chain network members of the supply chain and the construction of sustainable supply chain network. Based on the knowledge mapping, this study is still relatively macro and cannot cover all areas of supply chain management. This study only investigated the state of correlational research in WOS and Google Trends and not additional databases. However, the research on dynamic network relationship and structure measurement is still lacking.

Lot‐sizing policies for deterioration items under two‐level trade credit with partial trade credit to credit‐risk retailer and limited storage capacity

The main purpose of this article is to investigate the optimal wholesaler's replenishment decisions for deterioration items under two levels of the trade credit policy and two storage facilities in order to reflect the supply chain management situation within the economic order quantity framework. In this study, each of the following assumptions have been made: (1) The own warehouse with limited capacity always is not sufficient to store the order quantity, so that a rented warehouse is needed to store the excess units over the capacity of the own warehouse; (2) The wholesaler always obtains the partial trade credit, which is independent of the order quantity offered by the supplier, but the wholesaler offers the full trade credit to the retailer; (3) The wholesaler must take a loan to pay his or her supplier the partial payment immediately when the order is received and then pay off the loan with the entire revenue. Under these three conditions, the wholesaler can obtain the least costs. Furthermore, this study models the wholesaler's optimal replenishment decisions under the aforementioned conditions in the supply chain management. Two theorems are developed to efficiently determine the optimal replenishment decisions for the wholesaler. Finally, numerical examples are given to illustrate the theorems that are proven in this study, and the sensitivity analysis with respect to the major parameters in this study is performed.

The optimal cycle time for deteriorating items under retailer partial trade credit policy in supply chain

Most dominant retailers can obtain the full trade credit offered by the supplier but these retailers only offer the partial trade credit to their customers. Thus, Huang and Hsu [2008. International Journal of Production Economics 112, 655-664] investigated the retailer's inventory policy under two levels of trade credit to reflect the supply chain management situation. In their model, it is assumed that the retailer receives the payment from the last customer at the time N and the goods are not perishable.In this paper, we extend the work of Huang and Hsu (2008) by taking the deterioration rate into account and modifying the assumption of payment receiving time. We change original time N, which is the payment of the last customer, to the correct time N + T. Two theorems are developed to determine the optimal cycle time and numerical examples are given to illustrate the results.

Analysis of partial trade credit financing in a supply chain by EOQ-based inventory model for exponentially deteriorating items

In the classical inventory (or) supply chain models, it was assumed that the retailers and their customers must pay for the items as soon as the items are received. However, in practice, the supplier usually is willing to provide the retailer a full trade credit period for payments and the retailer just offers the partial trade credit period to his/her customers. This paper develops economic order quantity-based inventory model to investigate the retailer’s inventory policy for deteriorating items under two levels of trade credit in a supply chain management situation as a cost minimisation problem under partial trade credit option to their customers. Mathematical theorems, lemmas and algorithms are developed to efficiently determine the optimal inventory policy for the retailer. We deduce some previously published results of other researchers as special cases. Finally, numerical examples are given to illustrate the theorems and obtain a lot of managerial phenomena.

In this paper, it is assumed that the retailer maintains a powerful decision-making right and can obtain the full trade credit offered by the supplier yet retailer just offers the partial trade credit to his/her customers. Under these conditions, the retailer can obtain the most benefits. Then, we model the retailer’s inventory system as a cost minimization problem to determine the retailer’s optimal replenishment decisions under the supply chain management. Some easy-to-use theorems are developed to efficiently determine the optimal replenishment decisions for the retailer. We deduce some previously published results of other researchers as special cases. Finally, numerical examples are given to illustrate the theorems obtained in this paper. Then, as well as, we obtain a lot of managerial phenomena from numerical examples.

A Production Lot-Size Model for Perishable Items Under Two Level Trade Credit Policy for a Retailer with a Powerful Position in a Supply Chain System

This paper investigates a production lot-size inventory model for perishable items under two levels of trade credit for a retailer to reflect the supply chain management situation. We assume that the retailer maintains a powerful position and can obtain full trade credit offered by supplier yet retailer just offers the partial trade credit to customers. Under these conditions, retailer can obtain the most benefits. Then, we investigate the retailer's inventory policy as a cost minimization problem to determine the retailer's inventory policy. A rigorous mathematical analysis is used to prove that the annual total variable cost for the retailer is convex, that is, unique and global-optimal solution exists. Mathematical theorems are developed to efficiently determine the optimal ordering policies for the retailer. The results in this paper generalize some already published results. Finally, numerical examples are given to illustrate the theorems and obtain a lot of managerial phenomena.

Analysis of a fuzzy economic order quantity model for deteriorating items under retailer partial trade credit financing in a supply chain

This paper investigates the economic order quantity (EOQ) — based inventory model for a retailer under two levels of trade credit to reflect the supply chain management situation in the fuzzy sense. It is assumed that the retailer maintains a powerful position and can obtain the full trade credit offered by the supplier yet the retailer just offers a partial trade credit to customers. The demand rate, holding cost, ordering cost, purchasing cost and selling price are taken as fuzzy numbers. Under these conditions, the retailer can obtain the most benefits. Study also investigates the retailer’s inventory policy for deteriorating items in a supply chain management situation as a cost minimization problem in the fuzzy sense. The annual total variable cost for the retailer in fuzzy sense is defuzzified using Graded Mean Integration Representation method. Then the present study shows that the defuzzified annual total variable cost for the retailer is convex, that is, a unique solution exists. Mathematical theorems and algorithms are developed to efficiently determine the optimal inventory policy for the retailer. Numerical examples are given to illustrate the theorems and the algorithms. Finally, the results in this paper generalize some already published results in the crisp sense.

The main purpose of this paper is to investigate the retailer’s inventory policy under two-level delay permitted to reflect the supply chain management situation. In this paper, we assume that the retailer maintains a powerful position. So, it is assumed that the retailer can obtain the full trade credit offered by the supplier yet the retailer just offers the partial trade credit to his customers. Under these conditions, the retailer can obtain the most benefits. Then, an algebraic approach is provided to investigate the retailer’s inventory system as a cost minimization problem to determine the retailer’s optimal inventory policy under the supply chain management. One ease-to-use theorem is developed to efficiently determine the optimal inventory policy for the retailer. Finally, numerical examples are given to illustrate the theorem.

An EOQ model under retailer partial trade credit policy in supply chain

The main purpose of this paper is to investigate the retailer's inventory policy under two levels of trade credit to reflect the supply chain management situation. In this paper, we assume that the retailer has the powerful decision-making right. So, we extend the assumption that the retailer can obtain the full trade credit offered by the supplier and the retailer just offers the partial trade credit to his/her customer. Then, we investigate the retailer's inventory system as a cost minimization problem to determine the retailer's optimal inventory policy under the supply chain management. Two easy-to-use theorems are developed to efficiently determine the optimal inventory policy for the retailer. We deduce some previously published results of other researchers as special cases. Finally, numerical examples are given to illustrate the theorems and obtain a lot of managerial phenomena.

Supply chain model for the retailer's inventory policy under two levels of trade credit

The main purpose of this paper is to investigate the retailer's inventory policy under two levels of trade credit to reflect the supply chain management situation. All previously published models implicitly assumed that the supplier would offer the retailer a delay period but the retailer would not offer the trade credit period to his/her customer. That is one level of trade credit. In most business transactions, this assumption is debatable. Recently, Huang (2003) assumed that the retailer also adopts the trade credit policy to stimulate his/her customer demand to develop the retailer's inventory model. That is two levels of trade credit. Furthermore, we assume that the retailer's unit selling price and the purchasing price per unit are not necessarily equal. This viewpoint can be found in Teng (2002). Under these conditions, we incorporate Huang (2003), and Teng (2002) to investigate the retailer's inventory system as a cost minimization problem to determine the retailer's optimal inventory policy under the supply chain management. Then two ease-touse theorems are developed to efficiently determine the optimal inventory policy for the retailer. Finally, numerical examples are given to illustrate these theorems obtained in this paper.
