The document discusses several key concepts in production management: 1) Dispatch function executes production plans by transmitting manufacturing orders from the scheduling department to production shops and workers. 2) Tool control determines tool requirements, procures the necessary tools, and manages tool inventory to facilitate production and limit costs. 3) Routing determines the sequence of operations that transform raw materials into finished products as they flow through a plant. It aims to establish an optimal workflow.

- 1. 26 Jul Dispatch Function in Production Management Meaning of Dispatching Dispatch function executes planning function. It is concerned with getting the work started. Dispatching ensures that the plans are properly implemented. Dispatching is the physical handing over of a manufacturing order to the operating facility (a worker) through the release of orders and instructions in accordance with a previously developed plan of activity (time and sequence) established by the scheduling section of the production planning and control department. Dispatcher transmits orders to the various shops. Dispatch function determines, by whom the job shall ... 0 Comments Operations Management 26 Jul Tool Control in Production Management Meaning of Tool Control Tool control implies (1) determining tool requirements (2) procuring necessary tools and (3) controlling/maintaining tools once they have been procured. A tool or process planner must calculate tool requirements prior to the time of production to ensure that proper tools will be available when needed. Lost time resulting from incomplete tools planning can be expensive as well as causing work to delay. In order to facilitate tool control and to limit the investment in tool inventory, it is important to standardize wherever possible all the tools within an ... 0 Comments Operations Management 26 Jul Routing in Production Management Meaning of Routing Routing lays down the flow of work in the plant. It determines what work is to be done and where and how it will be done. Taking from raw material to the finished product, routing decides the path and sequence of operations to be performed on the job from one machine to another. The purpose of Routing is to establish the optimum sequence of operations. Routing is related to considerations of layout, temporary storage of in-process inventory and material handling. Routing in continuous industries does not present any problem because of the product type of layout, where the ... 0 Comments Operations Management 26 Jul Meaning of Reliability and Maintainability
- 2. Reliability Reliability may be defined as the probability, or degree of confidence that a product will perform a specified number of times under prescribed conditions. For example, the reliability of an electrical changeover switch may be defined as 0.9999. This may hold true only when it is operated with an input voltage of 440 volts AC, in an environmental temperature range of 0 to 80 degrees C, with humidity less than 90 percent, if its housing has never been opened, if it has been operated less than 1 million times, and if its is less than five years old. Even if any one of these ... 0 Comments Operations Management 25 Jul Quality Management Tools: Pareto Analysis Pareto analysis is a very simple technique that helps a manager to choose the most effective changes to make. It is represented as a bar graph used to arrange information in such a way that priorities for process improvement can be established. Pareto charts are constructed to provide a before-and-after comparison of the effect of control or quality improvement measures. The Pareto Effect The 80:20 theory was first developed in 1906, by an Italian economist, Vilfredo Pareto, who observed an unequal distribution of wealth and power in a relatively small proportion of the total population. ... 0 Comments Operations Management 20 Jul Quality Management Tools: Ishikawa Diagrams or Fishbone Diagrams Cause and Effect diagram are a graphical method for finding the most likely causes for an undesired effect. The Cause and Effect diagram also known as the fishbone diagram or Ishikawa diagram after its creator Kaoru Ishikawa is used to systematically list all the different causes that can be attributed to a specific problem (or effect). A cause and effect diagram can help identify the reasons why a process goes out of control. The Ishikawa diagram is one of the seven basic tools of quality control, which include the histogram, Pareto chart, check sheet, control chart, cause-and-effect ... 0 Comments Operations Management
