The applicability of manufacturing planning and control methods differs between environments. This paper explains the ®t between the planning environment and material and capacity planning on the detailed material planning and shop̄oor planning levels. The study is based on a conceptual discussion and a survey of 84 Swedish manufacturing companies. Results show the use of planning methods and th...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...
In many organizations, production planning is part of a hierarchical planning, capacity/resource allocation, scheduling and control framework. The production plan considers resource capacities, time periods, supply and demand over a reasonably long planning horizon at a high level. Its decision then forms the input to the more detailed, shorter-term functions such as scheduling and control at t...
the main purpose of the present study was to investigate the relationship between listening proficiency and metacognitive listening strategies awareness among low, mid, and highly self-regulated students. three hundred and seventy one efl students participated in this study (all grade 3 and 4 high-school students who were studying in khansar in academic year 1391-92). to gather the data, three ...
The application of group technology to production systems has in many firms led to the introduction of cellular manufacturing. This paper studies the changes that are required in the organization of the planning and control systems when applying cellular manufacturing. We review existing frameworks for designing such a planning and control system and propose a new framework that gives attention...
Abstract: This paper aims at presenting a structure of implementation the Workload Control (WLC) approach on commercial discrete event simulation software by comprehensively demonstrating how to construct and simulate this approach. research was developed considering lack studies fully describing kind software, which hinders dissemination use WLC managers. Initially, logic dedicated structured ...
