Supply chain management is important for companies and organizations to improve their business and lead competitiveness in the global marketplace. But demand variations in the supply chain are significant problem for most practitioners, planners, demand managers, and operations managers. Demand variations make forecasting and inventory management m...

Drilling machines are widely used in manufacturing plant. So it is very essential to know the effect of controllable parameters on the desired outputs. Otherwise, the random setting of the drilling parameters not only affects the desired quality but also increases the downtime by hampering the tool life. After considering these facts an experiment...

Recent global changes have prompted manufacturers to shift their production systems to make-to-order (MTO) supply chain (SC), enabling them to adapt customised customer requirements with their rapidly changing behaviours, reduce inventory costs, and obtain competitive advantages in the market. However, traditional MTO-based scheduling approaches fa...

Since production efficiency and costs are directly affected by the ways in which jobs are scheduled, scholars have advanced a number of meta-heuristic algorithms to solve the job shop scheduling problem (JSSP). Although this JSSP is widely accepted as a computationally intractable NP-hard problem in combinatorial optimization, its solution is essen...

This study introduces a bi-objective integrated supply chain (SC) scheduling (SCS) model to deal with the challenges of providing highly customized and on-time delivery requirements at the least cost. To address these real-life challenges, the model integrates the supply portfolio into production scheduling with a customer-imposed delivery time win...

This paper develops a multi-operator based differential evolution with a communication strategy (MCDE) being integrated with a sequential Tabu Search (MCDE/TS) to solve the job shop scheduling problem (JSSP) with the objective of minimizing makespan. The three variants of DE which are implemented in the proposed algorithm evolve as independent sub-...

The effectiveness of the finished component in turning process is highly reliant on the parameters related to the workpiece and cutting tool. This paper aims to assess the impact of machining parameters on tangential, radial and axial forces while turning AISI 201 stainless steel using cemented carbide tool insert. Process parameters such as spindl...

Improved turning performance is critical for higher quality goods to be manufactured and costs to be reduced. The objective of this paper is to determine the optimal cutting parameters that minimize the net force in turning AISI 201 stainless steel using different mathematical optimization algorithms. Spindle speed, feed, depth of cut, and workpiec...

Nowadays the uses of the Liquefied Petroleum Gas (LPG) increases in households and industries because of its availability and less cost. Because of leakage from the LPG carrying cylinder, severe accidents and life losses can occur. To avoid these losses, we propose and prototype a device, which will deliver an alarm and also control the leakage by...

Nowadays it has become a common phenomenon that due to LPG (Liquefied Petroleum Gas) leakage a huge loss of property even life loss occurs. To avoid these losses we made an LPG Leakage Detector and Controlling Device which will provide security with an alarm when the sensor will sense LPG, additionally there will be a red LED light to visualize the...

The present study is to develop an interactive possibilistic environment-based genetic algorithm for multi-product and multi-period aggregate production planning (APP). APP is the prerequisite in order to make material requirement planning and/or capacity requirement planning accurately. The present study attempts to minimise the production cost an...

Metal removal process is the most prominent secondary manufacturing process in which drilling is one of the most demanding one because a completely machined geometry and surface are generated in one operation. The demands in regard to diameter precision, straightness, and surface quality are enormously high. To meet those customer demands the cutti...

Smooth implementation and controlling conflicting goals of a project through using all related resources by an organization is inherently a complex task to management. Meanwhile, deterministic models are never efficient in practical project management (PM) problems because the related parameters are frequently fuzzy in nature. The project execution...

Decision making and choosing the right decision is one of the main activities of businessmen. Taking a decision without proper knowledge and methods the performance of the business will reduce and businessmen will fail to earn optimum profit. Facility location selection is the fast and foremost decision of businessmen when starting a new supplying...

The present condition of the Bangladeshi film industry is not as good as compared to other countries’ film industry like Hollywood, Bollywood, Chinese, etc. This industry is plunging day by day as though it reflects not only one country’s people, their customs, society, etc., just like a window of a society but also a huge amount of profit can be e...

The aim of this paper is to determine the best turning process parameters that give the optimal magnitude of chip thickness ratio and cutting forces of cylindrical mild steel bar under turning operation. There were total 27 experimental combinations for the three machining parameters i.e. Spindle speed, Feed rate and Depth of cut in three levels. F...

Scheduling has to consider operations sequences, machine load and availability of machines. Its aim is to optimize the objectives with the allocation of resources to tasks within the given time periods. A typical flow shop scheduling problem involves the determination of the order of processing of jobs with different processing times over different...

Project management decision issues have long attracted interest from both practitioners and academics. It is the process of planning, scheduling and controlling a combination of interrelated activities with conflicting objectives. That’s why a decision maker (DM) must simultaneously consider various conflicting objectives with respect to the imprec...
