The Job-shop scheduling considered the most significant industrial activities, mostly in manufacturing. The JSSP (Job Shop Scheduling Problems) is typical NP-hard problem. To solve this problem, we have used the linear programming approach. Real data have been taken from the company of the metalworking industry. The model has been created, then it was analyzed using Spreadsheet-Excel Solver. The appropriate sequence has been obtained and the results shown that it is possible to achieve the minimum completion time compared to other sequence combination

Thus, this study is carried out to present the importance of CAD/CAE system on process of design and process of optimization of spur gear. The paper presents the usage of CAD system for modeling parts and CAE software for analysis of stress-strain of spur gear and the results of calculation of pair spur-gears that it used in the gearbox transmission of the bucket wheel excavator located in "Bardhi i Madh-Fushë Kosovë", and after that will be optimized the shape of the spur gear with usage of ANSYS software. Consequently, the aim of this research is to calculate stress-strain structure of parts (gears) and reduce weigh of the gears.

Digitalization of factory has impact the entire business environment and lead to Smart Enterprises. To create a model of Smart Factory, first we have analyzed the existing situation of Kosovo Manufacturing Industry with regard to revolution of Industry. In this paper we will describe the results of a recent research at the Kosovo manufacturing companies and are included metalworking and furniture industry, where is developed a Maturity Level for Kosovo Industry. To describe the Maturity Level of Kosovo Industry we have delivered questionnaire and have been done interviews with CEOs (Chief Executive Officer). The average score of Industrial Maturity Level for Kosovo Industry is 2.14 which represent 2nd Industrial Revolution, but some of enterprises belong to 3rd Industrial Revolution. Also, the main barriers of this low level of Maturity Level of Kosovo Industry are highlig...
