In this paper we investigated guaranteeing the assembly process information flow in real time, enterprise wide, from assembly station sensors directly to the company policy maker's offices, is the true solution for improving productivity competence, reducing bottlenecks movements, optimization of supply chain network, identify missing operations in the floor process and more over reducing losses and greater profits than ever. In fact, the ideal production lies in the real machine or assembly capabilities of working non-stop at maximum speed, lacking downtimes or inactivity and assembled goods reject threats. Assembly lines will be prone to stand-still and will produce defective pieces if the machines are unable to working to their full capability or demands made of them. This is often the case of misinformed factory management on real time factory floor performances. Even though equipped with original equipment manufacturer indicator knowledge about their systems, they still can't get that efficiency so needed to improve yield. Transformation is necessary to ride the expected tide of change in the current manufacturing environment, particularly in the information technology and automation landscape. Multinational company's strives to reduce computing costs, to improve plant floor visibility and to achieve more efficient energy and surroundings use of their IT hardware and software investments. Cloud computing infrastructure accelerates and promotes these objectives by providing unparalleled flexible and dynamic IT resource collection, Virtualization, floor visibility and high accessibility. This paper establishes the value of realizing cloud connect and usage state of affairs in the cloud manufacturing environment, especially in automotive assembly stations which typically have large numbers of mixed applications, various hardware and huge data amount generated from sensors and devices in real-time and event-based exploration and assembly operations. The purpose of this paper is to behavior an Information Technology automotive assembly environment Systems analysis in the case of MNC's. To validate this objective, the article has been divided into two parts: monitoring vision and control and case study with the help of the manufacturing execution assembly system. The purpose of the theory part of the study is to first introduce the concept of Cloud connect in the respective field of manufacturing execution assembly system, and then chat about the substance of Service management in information technology. © 2005 - 2013 JATIT & LLS.
