“…The most suitable model among considered is the model of Hopp and Spearman (2008). It is also worth noting that several distinguishing features were taken from "lost sales (r, Q) inventory control model" (Kouki et al, 2015), classical (r, Q) models of Bookbinder and Cakanyildirim (1998) and Bijvank and Vis (2011). The considered model makes several assumptions.…”

The paper describes an eventual combination of discrete-event simulation and genetic algorithm to define the optimal inventory policy in stochastic multi-product inventory systems. The discrete-event model under consideration corresponds to the just-in-time inventory control system with a flexible reorder point. The system operates under stochastic demand and replenishment lead time. The utilized genetic algorithm is distinguished for a non-binary chromosome encoding, uniform crossover and two mutation operators. The paper contains a detailed description of the optimization technique and the numerical example of six- product inventory model. The proposed approach contributes to the field of industrial engineering by providing a simple, but still efficient way to compute nearly-optimal inventory parameters with regard to risk and reliability policy. Besides, the method may be applied in automated ordering systems.

“…Some papers consider deterministic lead-time for technical tractability. For instance, Kouki et al (2015) study a perishable inventory system that operates under stochastic demand and a constant lead-time. They characterize the properties of the cost function and present an approximation procedure to find the policy parameters.…”

“…Some scholars previously have done certain related researches about the shortage, surplus, replenishment of fresh agricultural products. Chaaben Kouki et al (2015) [1] proposed inventory control model, which contributed to the literature by providing a simple and efficient algorithm to compute the best (r, Q) parameters that minimized the total cost. Yiyan Qin et al (2014) [2] considered the pricing and lot-sizing problem for products with quality and physical quantity deteriorating simultaneously, and designed the optimal model to investigate the deterioration inventory of fresh produce and foods.…”

The purpose of this research is to minimize the total cost of the overall system in the process of replenishment, to maximize the overall system profits. This paper regards all affiliated stores of chain supermarket as a system to do some research about the replenishment of fresh agricultural products. Then, this paper proposes the lateral replenishment strategy, analyzes its advantages, and applies the strategy thinking to the solution of the surplus or shortage of fresh agricultural products. Through the establishment of the inventory cost model, we compare the system inventory total cost between taking the lateral replenishment and deployment strategy and not using the lateral replenishment and deployment strategy, and get that there is lower total cost. Through the establishment of lateral replenishment transportation model, the optimal dispatching scheme between the surplus supermarket and the shortages supermarket is given. And then, the sensitivity analysis presents the variable range of the fresh agricultural products increment and decrement that does not affect this optimal dispatching scheme. This paper can provide a reference for the chain supermarket to deal with the shortage or surplus of fresh agricultural products so as to improve sales margins of agricultural products, to reduce the total inventory costs of the whole the chain supermarket system, and to improve the customer service levels.
