Supply Chain Collaboration is the network of various entities that work cohesively to make up entire process. The supply chain organizations’ success dependent on integration, teamwork, and communication information. Every day, business players in a dynamic setting. They must balance competing goals such as process robustness, risk reduction, vulnerability real financial risks, resilience again...

The mathematical analysis for estimating the performance rate "RP" of chain-type trenching machine was studied. ended with an equation this type. This checked under different operating conditions. practical study showed that deviation theoretical from actual ranged -3.4 to +2% only 150.7 cm and 120.7 trench depth respectively. field efficiency 46.7 57% It also increase in by decreasing depth.

Frame saw machine is one of tools that used to process dimension stone. The velocity fluctuation traditional feed drive system (FDS) lead excessive wear diamond particles. dynamic performance the FDS has time-varying characteristics during processing stone with a large material removal rate. In this paper, novel was proposed. Firstly, modeling set up on account lumped parameter method (LPM). Th...
