a manufacturing process cannot be released to production until it has been proven to be stable. also, we cannot begin to talk about process capability until we have demonstrated stability in our process. this means that the process variation is the result of random causes only and all assignable or special causes have been removed. in complicated manufacturing processes, such as drilling proces...

this paper presented a mixed integer programming for integrated scheduling and process planning. the presented process plan included some orders with precedence relations similar to multiple traveling salesman problem (mtsp), which was categorized as an np-hard problem. these types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...

Purpose – To provide an update on a paper published in 1987 in IJOPM. Design/methodology/approach – Provides an assessment and update of “An agenda for research on the flexibility of manufacturing processes”. Findings – Gerwin’s seminal work added welcome rigor to a concept, manufacturing flexibility, which had gained prominence during the previous decade. Finds that many of Gerwin’s insights h...

Because of increasing competition and cost pressure, the manufacturing industry is currently undergoing massive changes that are facilitated by the usage of Information Technologies. Two particular aspects are the usage of Business Process Management (BPM) and Cloud technologies concepts in the manufacturing domain. Rapid elasticity is crucial for the enactment of manufacturing processes in the...

It is also done a brief presentation of the data structure used to monitor the manufacturing cell status, and it is explained its achievement and its philosophy by a complete flowchart. 1.Introduction and brief description The monitoring process of the manufacturing cell deals with the ...

The purpose of this paper is to apply TRIZ for solving the GSC problems in Sobhanoncology pharmaceutical firm. A review of the past papers of TRIZ based methods to GSC problem resolution is presented. The TRIZ contradiction matrix tool which was applied to the specific problem brings many benefits e.g.: being rapid acceleration in solving the problem. Moreover provides repeatability, reliabilit...

Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...

the paper presents a new computational technique for the manufacturing process planning in laser cutting robotic systems. It focuses on the optimisation of robot motions for continuous contour tracking using the redundancy caused by the tool axial symmetry. In contrast to previous works, the developed technique is based on the dynamic programming and explicitly incorporates verification of the ...

Metal-based additive manufacturing processes require a supporting of overhanging part areas during the powder solidification e. g. for improving the heat dissipation to the substrate. Technology users nowadays strive to reduce support areas due to economical aspects, while simultaneously enhancing the process stability by maximizing the support stiffness. For the simplification and acceleration...
