“…The model developed to minimize the total cost was analyzed by Ant Colony Algorithm and it was found that Ant Colony Algorithm is more effective than Particle Swarm Optimization Algorithm. Ghasimi and Ghodsi [7], offers three new inventory control models for perishable products in the JIT supply chain. The model aims to minimize the total cost of the entire supply chain, including production, transportation, stock, early and late delivery, and the cost of processed goods.…”

Just-in-time (JIT) delivery is one of the key delivery strategies that enable the right quality product to reach the point of demand at the right time without creating unnecessary costs in the supply chain network. The concepts of quality and time are two main factors to be considered in this issue. Particularly because the variability in quality directly affects cost and time, it is very important for JIT delivery. In this study, the effect of raw material quality within the supply chain network which tries to ensure JIT delivery is examined. For this, a multi-stage, multi-period mixed-integer mathematical model is proposed in the study. The model aims to minimize the total supply chain cost by trying to balance the purchasing and quality costs for manufacturers. In addition to standard constraints, the stock balance and time constraints have been developed for JIT delivery. As a result of the model resolved with the GAMS Distribution 21.6 program, 34.5% of the raw material supplied from suppliers is provided from 1st quality raw materials, while 65.5% is provided from 2nd quality raw materials. Despite its low purchasing costs, 3rd quality raw material has not been preferred by the producers in any period because it causes a delay in JIT delivery. Besides, it is seen that deliveries are made very close to the maximum delivery time of distribution centers, depending on the variability in raw material quality. It is understood that raw material quality is an important concept in a JIT supply chain network due to its significant impact on time.

Purpose – The fundamental concept behind Just in Time (JIT) is to provide the right product at the right time and in the required quantity, reducing inventories in warehouses and in manufacturing processes. On the other hand, it requires increased usage of transport vehicles, which may negatively affect the organization's environmental sustainability indicators. In order to contribute to discussions on the subject, this study aims to identify, systematize and analyze the available literature on the intersection of JIT and Environmental Sustainability topics. Design/methodology/approach – A structured literature review was performed through research in the Scopus and Web of Science databases. Fifty-three papers published in journals or at congresses were identified and analyzed. Findings – The selected papers were categorized in five dimensions: environmental aspects, operational costs, operational performance, research method and location/region of the study. A lack of consensus was identified on whether or not logistics operations favor sustainable practices that used the JIT system. Originality/value – To build on the analysis and discussions on the JIT and Environmental Sustainability and support future research on the subject, the study has classified 53 selected papers based on their purposes in five different dimensions. Given that organizations need to become increasingly sustainable, a SWOT (strengths, weaknesses, opportunities, and threats) matrix has been prepared in addition. Keywords - Just In Time, Transport, Environment; Sustainability; Logistics.
