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 be done and it co-ordinates production. It is the key point of a production communications system. It creates a direct link between production and sales.

A dispatcher is familiar with the productive capacity of each equipment. He always keeps an eye over the progress of orders which move at different speeds on different routes.

Dispatch Procedure

The product is broken into different components and components into operations.

1. Store Issue Order: Authorize stores (department) to deliver required raw material.

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 organisation.

Need for Tool Control

It is very important to ensure:

• Against loss through theft or negligence and production delays through misplacement or non-availability of tools.
• That the investment in tool inventories is minimized consistent with proper tool availability.

Tool Control Procedure

Two methods are commonly used to control the issue and receipt of tools to and from the workers.

1. The Brass Ring System. Brass rings with worker’s identification number marked on them are issued to every worker when he draws a tool from the crib, he gives one of his, rings to the attendant and the ring is hung on a peg at the tool bin.

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 equipment is laid as per the sequence of operations required to be performed on the components (from raw material to the finished products). In open job shops, since, every time the job is new, though operation sheets (sometimes) may serve the purpose, but the route sheets will have to be revise and this involves a greater amount of work and expertise.…
