Application of Petri Nets in Material Supply Systems

Abstract

With the increasing Scale of the business and the cost of production in the market environment, enterprises have to consider internal and external organizational boundaries to find different angles that enhance the supply of customers, and it applied for method of subordinate units also. In particular, the theory of process reengineering based on supply chain management which is not mature yet. As for the supply chain management changes into business process reengineering environment, Traditional business process itself which needs to expand. In this paper, firstly, it introduces basic concepts of the Petri nets. Secondly, it introduces the concurrency, clash, bumping and how it describes the linkages between the events. What's more, it describes application of Petri nets in the material supply system. Finally, it takes a unit in particular stage material demand information processing, for example, modeling and analysis the situation to explain the Petri nets, which application in the material supply system.

Efficacy and Biochemical Evaluation of Two Nano materials in Control of Cotton Leafworm, Spodopetra littoralis

“…Also, both Silica late and Silver late increased the Also, both Silica late and Silver late increased the activity of beta esterase enzymes 45.925% and 40.46% higher above the control level, respectively. The obtained results matched with [29] findings in Gharbia, alpha -esterase activity increased. Concluded that both alpha and beta esterase in S. littoralis was highly inhibited with hexaflumuron.…”

“…After centrifugation, the supernatant fluid was divided into small aliquots (0.5 ml) and stored at -20 °C until analysis. The Biochemical analysis were the following: a) determination of total protein content [28], b) determination of Chitinase activity [29] and c) determination of non-specific esterases activities [28].…”
