“…An EOQ inventory model was developed by Shukla et al [12] with quadratic demand that permitted both payment delay and shortages. Tripathi and Manjit Kaur [13] considered an inventory model with deteriorating items to be a phenomenon that cannot be overlooked, as failing to consider such context may provide an absurd result. In the high-tech business industry, deterioration is not necessarily constant, but rather time-dependent.…”

. Inventory models with integrated time-dependent demands for deteriorative items are considered in this study. The demand models found in the literature include constant, linear, quadratic, exponential, price dependent, and stock dependent among others. To wit, no study exists that uses integrated time-dependent demands. Three models are developed: The first model uses continuously compounded demands, the second model uses linear demands integrated with continuously compounded demands, and the third model uses quadratic demands integrated with continuously compounded demands. Mathematical models are delineated for each model and relevant examples are provided to elucidate the proposed procedure. The objective herein is to obtain optimum order quantities and order intervals concerning the overall cost. Sensitivity analysis is provided for each of the three models. The necessary data was generated using Visual Basic 6.0.. Inventory models with integrated time-dependent demands for deteriorative items are considered in this study.

“…In recent years, an integrated assessment of the suppliers, producers, distributors and consumers that make up the supply chain components is one of the areas that has received much attention (Pandey et al, 2017;Rastogi et al, 2017;Shah, 2017;Tripathi & Kaur, 2017). From an operational point of view, supply chain management integrates suppliers, builders, warehouses and storage facilities in a manner that is effective in producing and distributing goods at the right time and in the right place, and maintaining the total cost of the system while maintaining the appropriate level of service to the customers (Glock, 2012).…”

In this paper, a mathematical model for multi-product inventory management in a three-tier supply chain consisting of multi-supplier, a manufacturer, and several retailers is presented. The model determines different factors such as the optimum ordering of the raw materials and the optimal level of the production items with the optimal order of the products by retailers at each level of the chain, with the objective of minimizing inventory management costs in the supply chain. An algorithm is presented to determine the solution of the problem and the implementation of the proposed method is demonstrated using some numerical example.
