Research on the Flexible Job Shop Scheduling (FJSP) problem in manufacturing process of aircraft engines has been carried out. It is found that there are real requirements such as order mandatory nodes and equipment selection current job scheduling process. Order node means some important orders must be delivered time at a certain point time, which often affects quality workshop results. In add...

The scientific foot is directed towards a range of net-zero paths, which can predict the sustainable future society. Climate neutral practices require ultimate plan action for people, planet, and prosperity. It critical to set synergy among education, industry, government policies creating clear vision evolve various sectors addressing utilization climate neutrality objectives on regional basis...

We propose a new approach to analyze multiclass queueing systems in heavy traffic based on what we consider as fundamental laws in queueing systems, namely distributional and conservation laws. Methodologically, we extend the distributional laws from single class queueing systems to multiple classes and combine them with conservation laws to find the heavy traffic behavior of the following syst...

In this paper we demonstrate that the distributional laws that relate the number of customers in the system (queue), L (<?) and the time a customer spends in the system (queue), S (W) under the first-in-first-out (FIFO) discipline lead to a complete solution for the distributions of L, Q, S, W for queueing systems which satisfy distributional laws for both L and Q {overtake free systems). Moreo...
