Opis:
This study investigates an inventory model for deteriorating products with a price and stock-dependent demand pattern where the holding cost is a non-linear function of both time and stock level. Moreover, a decreased price and a higher stock level lead to a higher rate of demand. Consequently, in this article, we present a new approach, aiming at maximization of the return on investment by maximizing the profit/cost ratio. If an inventory manager has the potential to invest in a variety of projects, but disposes of only limited resources, it is logical to strategically plan towards a better return on investment. As a result, the manager’s objective will be to develop an inventory policy with a possibly high return on investment. Therefore, a new strategy is considered in this article to optimize the profitability ratio in terms of replenishment time and selling price, which is determined as the proportion between the profit and the overall cost of the inventory scheme. This research demonstrates that optimizing the profitability ratio is equivalent to decreasing the average inventory cost of a product per unit. Also, the optimality is graphically checked and one numerical illustration is discussed to explain the result of the proposed model. Finally, sensitivity analysis of key parameters is performed to show the applicability of the proposed model. The profit/cost ratio is more sensitive to price elasticity markup or purchasing cost compared to the other parameters used. Also, for decision-makers, several helpful management insights are derived.

Opis:
Financial capability is one of the primary drivers for buyers to make purchases. Therefore, sellers must set an optimum selling price and consider trade credit facilities to attract more demand. This paper proposes an inventory decision model in which customer demand depends on the price and number of credit installments to serve low-abled buyers. This study has developed a demand function with a positive impact on installment policies and the effect of the selling price. Two models have been formulated to optimize the selling price and positive stock time, m total profit, with and without installment policies. Then, numerical examples and sensitivity analysis illustrate the proposed model for different cases. The study has found that the selling price and positive stock time can be optimized. Profits can be higher in the case of an installment facility than in the case without an installment facility. It shows positive responses from the buyer to the installment policy.

Opis:
In this article, an attempt is made to optimize the joint total profit per unit time of vendor – buyer supply chain system where vendor offers different trade credit depends on order quantity to the buyer. Here items in the inventory are deteriorates with constant rate and demand is a linear function of time. Vendor is establishing threshold for allowing trade credit comprehensively to ensure the greatest benefit for both players. By analyzing total channel profit function, we developed the optimal solution to provide buyer’s order quantity and replenishment time. Numerical examples and sensitivity analysis are given to illustrate the theoretical results, and some managerial insights are also obtained.

Opis:
In the business world, it is generally observed that the supplier gives a cash discount due to advance payment. The buyer may either pay off the total purchase cost or a fraction of the total purchase cost before receiving the products. If the buyer makes full payment then he receives a cash discount instantly. If the buyer pays a fraction of the total purchase cost, then (s)he receives the cash discount while paying the remaining amount at the time of receiving the lot. Moreover, in most of the inventory models, it is generally assumed that the delivered lot contains only perfect items. But in reality, the presence of imperfect items in the received lot cannot be overlooked as it will affect the total profit of the system. Thus, the study of inventory models considering the presence of imperfect items in the lot makes the model more realistic and it has received much attention from inventory managers. This paper develops a model that jointly considers imperfect quality items and the concept of an advance payment scheme (full and partial). The objective is to determine optimal ordering quantity to maximise the total profit of the system. The necessary theoretical results showing the existence of global maximum is derived. The model is illustrated with the help of numerical examples, and sensitivity analysis is carried out on some important system parameters to see the effects on the total profit of the system. The study shows that a full advance payment scheme is beneficial for the buyer.

Opis:
This paper develops a three echelon supply chain inventory model with permissible delay in payment, in which distributor and retailer’s demand is time dependent and production rate for manufacturer is also time sensitive. The models consider the two level trade credit policy in manufacturer-distributor and distributor-retailer relationship in this supply chain model. A simple solution algorithm is presented to determine the optimal order quantity and optimal cycle time of the total cost function and the number of shipments for distributor and retailer. The results are discussed with numerical examples and the particular cases of the model are also discussed in brief.

Opis:
The present paper deals with an EOQ model for deteriorating items with time-dependent exponential demand rate and partial backlogging. Shortages are allowed and completely backlogged in this model. The backlogging rate of unsatisfied demand is assumed as a function of waiting time. The concept of penalty cost is introduced in the proposed model because there are many perishable products that do not deteriorate for some period of time and after that period they continuously deteriorate and lose their values. This loss can be incurred as penalty cost to the wholesalers/retailers. In any business organization, the penalty cost has an important role for special types of seasonal products and short life products. Therefore, the total cost of the product can be reduced by maximizing the demand rate and minimizing the penalty cost during a given period of time. The purpose of our study is to optimise the total variable inventory cost. A numerical example is also given to show the applicability of the developed model.

Opis:
The awareness of making decisions in an imprecise environment has resulted in considering the inventory system under a fuzzy approach. The effects of uncertain demand have been finding increased application in many inventory systems. Uncertainty creates complicated situations for the manufacturer in making decisions. Markets have become more competitive as a result of technological advancements. The effect of inflation on the overall cost of the inventory system is useful in providing a tool for the analysis of inventory decisions. This study intended to estimate the effect of different fuzzy numbers on a manufacturer's annual joint expected total cost. The comparative study of this proposed model has been considered for two different fuzzy numbers with the defuzzification technique as the centroid method. The optimization technique has been used to minimize the producer’s joint expected total cost under the condition mentioned earlier, and the model is validated numerically.

Opis:
The objective of this article is to maximize the joint profit for supplier and retailer by constructing a combined supplier–retailer inventory model wherein supplier and retailer both have implemented trade credit policies, and some defective items are received by the retailer. The customer’s demand is expressed as a function of time, price and credit period, which is appropriate for the products for which demand increases initially and after some time it starts to decrease. Production, directly proportional to the customer’s demand rate, is considered as one of the decision variables for the purpose of reducing the holding cost of the supplier. The article estimates the optimum replenishment cycle, customer’s credit period, retail selling price by a classical optimization technique. For validation of the derived model, various numerical examples are demonstrated. Finally, implementing sensitivity analysis on the decision variables by varying the inventory parameters, effective managerial insights are generated which is beneficial for the players of supply chain by practically gaining the maximum joint profit through advising to opt for the case N ≤ M ≤ T , i.e., when the customer’s trade credit period offered by the retailer is lesser than the retailer’s trade credit period offered by the supplier and which is lesser than the replenishment cycle length.

Opis:
Efficient management of supply chains consists in particular in ensuring possibly highest quality of customer service and striving for minimization of the costs generated by flow between the links. Typical cause of constantly increasing costs is excessive inventory levels throughout the chain. The reason for this situation is maladjustment of the level of supply to the level of demand in the market, which results in surplus stock. The starting point for reduction in inventory levels is forecasting of demand in the market through market prognoses in cooperation with all the links in the supply chain. Therefore, in the aspect of demand forecasting, the character of data flow and the type of cooperation between the links is essential.
Efektywne zarządzanie łańcuchami dostaw polega przede wszystkim na zapewnieniu możliwie najwyższej jakości obsługi klienta oraz dążenie do minimalizacji kosztów generowanych przez przepływ pomiędzy jego ogniwami. Typowymi przyczynami stale rosnących kosztów jest nadmierny poziom zapasów w całym łańcuchu. Powodem takiej sytuacji jest niedostosowanie poziomu dostaw do poziomu popytu na rynku, co prowadzi do gromadzenia nadmiernych zapasów. Punktem wyjścia do obniżenia poziomu zapasów jest prognozowanie popytu na rynku poprzez prognozy rynku we współpracy z wszystkimi ogniwami łańcucha dostaw. Dlatego też w aspekcie prognozowania popytu istotne są, charakter przepływu danych jak i rodzaj współpracy między poszczególnymi ogniwami.
