The equipment replacement problem plays a crucial role in various engineering disciplines. It helps to determine the optimal economic lifespan of equipment. Optimizing the decision-making process for equipment replacement is essential for enhancing management effectiveness and supporting the achievement of business goals. Numerous models have been...

This paper deals with optimizing Simple Exponential Smoothing for time series forecasting in supply chain management, particularly in the transport and automotive sectors. This paper attempts to enhance the accuracy of the forecast by estimating an optimal smoothing constant α with the Mean Squared Error as the objective function. This optimization...

The transportation problem is solved usually in three successive steps. These steps include: Finding the initial basic feasible solution, test of optimality, and moving towards optimality. There are many different methods that can be used to find the initial basic feasible solution. Out of these methods are: NorthWest Corner Method, Row Minima Meth...

Proper forecasting is imperative in making production, marketing, and inventory decisions in many fields, especially in the automotive industry. Different quantitative analysis techniques were applied in this study to predict demands in automotive spare parts for inventory management. The study is applied on a service station of a transportation co...

Accurate forecasting is applied to several industries, especially in automotive engineering, where tasks are prediction of car spare parts demands and estimation of maintenance works to optimize inventory levels and reduce costs. Traditional methods for forecasting, Moving Averages, and Exponential Smoothing often need to capture the dynamic nature...

The classical transportation problem aims at finding the optimal distribution of a certain product from different sources to different destinations. The objective of this optimal distribution could be minimizing the total transportation cost, time, distance or any other related single objective. In real world applications there are more than one ob...

This paper presents a solution algorithm to solve one class of bicriteria multistage transportation problem. This class represents bi-criteria multistage transportation problem without any restrictions on the intermediate stages. A way to find the non-dominated extreme points in the criteria space is developed. This method involves a parametric sea...

Due to the excess of a vehicle operation through its life, some elements may face failure and deteriorate with time. This leads us to carry out maintenance, repair, tune up or full overhaul. After a certain period, the vehicle elements deteriorations increase with time which causes a very high increase of doing the maintenance operations and their...
