The great variety of offerings from companies engaged in mass customization such as in the automotive sector, implies millions of end products. As in the case of carmakers, this variety proceeds from the combination of dozens of optional or alternative components whereby thousands or even millions of end products can be obtained. A number of technical or commercial constraints prevent most comb...

One of the primary factors that impact the master production scheduling performance is demand fluctuation, which leads to frequently updated decisions, thereby causing instability. Consequently, global cost deteriorates, and productivity decreases. A reactive approach based on parametric mixed-integer programming is proposed that aims to provide a set of plans such that a compromise between pro...

This chapter describes a methodology to reduce patient waiting time in a for-profit ambulatory surgical center. Patients in this facility are scheduled in advance for the various operations, and yet operations start late, last longer than expected creating undesired delays. Although this facility is limited to ambulatory surgery, it provides a large number of different surgeries, which are sche...

internal resorption is rare in permanent teeth. treatment is usually performed through warm gutta-percha technique. if the resorptive process perforates the root, treatment may be more difficult and is usually performed via surgical approach. non-surgical repair of a perforating internal root resorption with mta was conducted in this case. before repairing the resorption, a master gutta-percha ...

The purpose of this article is to propose a guide for the digital transformation (4.0) manufacturing SME’s medium-term production planning process, master schedule (MPS). A model current MPS process group SMEs presented as starting point toward digitization. state reveals lack tools support decision making and need increase reliability input data make more agile. Industry 4.0 technologies model...

The Position and orientation accuracy of robot manipulator has long become a major issue to be considered in its advanced application. The simplified expressions for the differential vector of the end-effector have been proposed based on the original expressions derived by Veitschegger and Wu in 1986. According to this new expression, a linear error model that described the end-effector positio...
