Storekeeping is a service function which deals with the physical storage of goods under the custodianship of a person called storekeeper or stock controller. Goods stored may be either, stores or stock. Unworked materials or raw materials are usually referred to as stores and the place where they are kept is known as stores room. Finished products ready for shipment are usually called stocks and are housed in a place called stock-room. Storekeeping, therefore, is that aspect of materials which is concerned with physical storage of goods. Store functions concern receiving, movement, storage and issue of items- raw materials, bought out parts, tools, spares, consumables etc. —required for production, maintenance and operation of the plant and finished goods until is dispatch to customers. Store, therefore, is the custodian of all goods that are received in the company until they are consumed or sold and naturally it assumes the responsibility of Continue reading

Preventive Maintenance
Preventive maintenance anticipates failures and adopts necessary actions to check failures before they occur. It includes activities like inspection, lubrication, cleaning unkeeps, minor adjustments and replacements found necessary at the time of inspection etc. Its purpose is to minimize breakdowns and excessive depreciation. Neither equipment nor facilities should be allowed to go to the breaking point. In its simplest form, preventive maintenance can be compared to the service schedule for an automobile. Preventive maintenance can be either: running maintenance or “shut down maintenance”. Running maintenance includes maintenance activities e.g. minor adjustments in machines revealed through inspections, lubrication, cleaning and upkeep etc., which are carried out when the machine is still running. Shutdown maintenance includes preventive maintenance activities such as minor component replacement whose needs are identified through inspections, which require stoppage of machines. Preventive inspection is one of the key activities of preventive maintenance which is usually performed by Continue reading
Tool Control in Production Management
Meaning of Tool Control Tool control in production management 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 Continue reading
Role of the Warehouse in Postponement Strategies
The rapid changes occurring in customer-supplier relationship has resulted in shortening the product life cycle along with the product variations, which could meet the complex customer satisfaction demands. As the customer requirements changes rapidly, it increases the complexity of planning and demand forecasting to suit the changing demands. Hence, postponement strategies are able to help in solving such complex issues. The strategy involves delay in the production process to the maximum possible time, while delaying the point of product differentiation. As the whole strategy is related to the value of information, it can be maximized with delay in production decision time, giving more time to receive and analyze the customer requirement and demand. Hence, the postponement strategies help in improving the quality of decision, while also optimizing the quality of product planning and demand forecast. The relevant strategy also allows for the flexibility in the production scheduling, where the actual Continue reading
Design for Manufacture and Assembly (DFMA)
Design for Manufacturing and Assembly (DFMA) method was introduced by Geoffrey Boothroyd since 1960s on automatic handling. This enables the use of gathered data of previously done mistakes, speeding up the development process and accomplishing new philosophies and technologies to further ensure that the activities that are quicker and more precise in generating results can really reach this target. All aspects of design, development, manufacturability, total parts, assembly time, cost and modularity are considered in this analytical process. This process mainly focuses on enhancing the product to allow improvements in the manufacturing, quality, reliability, cost, time to market, and many other fields. Integration of discrete but highly interrelated issues of manufacturing processes and assembly occurs in DFMA. Through its use companies can make the full use of manufacturing processes that exist while minimizing the number of parts in an assembly. Design for Manufacturing and Assembly (DFMA) is a system that Continue reading
Supply Chain Management Processes
Although there are many views of supply chain management (SCM), at present, many practitioners look upon SCM as the management of key business processes across the network of organizations that form the supply chain. A supply chain is a network of manufacturers, suppliers, distributors, transporters, storage facilities and retailers that perform functions like procurement and acquisition of material, processing and transformation of the material into intermediate and finished tangible goods, and finally, the physical distribution of the finished goods to intermediate or final customers. According to the definition given by the Global Supply Chain Forum, supply chain management is the integration of key business processes from end-user,to original suppliers that provides products, services, and information that add value for customers and other stakeholders. There are eight business processes that are carried out across the supply chain. They are: Customer Relationship Management: Customer relationship management involves establishing a framework for building Continue reading
