“…Yang [27] and Li [28] et al presents a new method by five step called critical chain multi-project management (CCMPM) by means of implementing the critical chain scheduling and buffer management into multi-project management. Furthermore, the critical chain project management Bayesian network model (CCPMBN) based on the critical chain project management and Bayesian network technologies was established by Shang [30]. Not after a long time, based on the analysis of basic theories of WBS and Bayesian networks, Li and Liu [29] establishes the critical chain project management bayesian network model for WBS-based and condition of the timing and resource constraints.…”

Abstract. The relationship between precedence and successor activities is the only factor that determined the project scheduling in the traditional project scheduling management. The critical chain-an elegant solution, on the other hand, takes resource limitations into account and is composed of sections that are dependent on successor relationships and other sections that are dependent on resource constraint. By integrating the existing research findings, it is the objective of this paper to highlight the merits and pitfalls of the CCPM scheduling method, such as the principle for project delays, the critical chain identification; the time buffer setting and project scheduling with limited capacity of a resource. Furthermore, it also presidents the difficulties when implementing the critical chain approach and conclude with a description of our ongoing research direction.

“…As an alternative material for space mirror, silicon carbide (SiC) ceramic has various excellent properties of high specific stiffness, thermal stability, and outstanding surface performance in optical processing. It attracts more and more attention and gradually becomes the major candidate for space mirror in recent years [1]. But SiC is also known as difficult-to-machine material due to its high hardness and brittleness.…”

Grinding force is an important indicator related to processing efficiency and residual strength in the progress of grinding SiC. With the method of ultrasonic assisted grinding (UAG), this paper studied the influence of four parameters on grinding force based on orthogonal experiment, namely vibration amplitude, depth of grinding, feed rate and spindle speed. A series of results with high efficiency and low grinding force were obtained. A regression empirical model under the condition of UAG was established and verified. It was also proved that ultrasonic vibration was conducive to improve the ground surface quality of workpiece.
