Identify the factors involved in a plant location decision. 7 Outline the advantages and disadvantages of maintaining large inventories. 8 Identify the steps in the production 4 Explain the major tasks of production and operations managers. control process. 9 Explain the benefits of quality control. • Production: Application of resources such as people and machinery to convert materials into finished goods and services. • Production and Operations Management: Managing people and machinery in converting materials and resources into finished goods and services. • A vital function is necessary for generating money to pay employees, lenders, and stockholders. • Effective production and operations management can: – lower a firm’s costs of production. – boost the quality of its goods and services. – allow it to respond dependably to customer demands. – enable it to renew itself by providing new products. • Mass Production – manufacturing products in large amounts through standardization, mechanization and specialized skills. • Flexible Production – producing smaller batches using information technology, communication and cooperation. • Customer-Driven Production – evaluating customer demands to link with manufacturer. • Robots – reprogrammable machines capable of performing routine jobs and manipulating material • Computer-Aided Design and Manufacturing – enables engineers to design parts and buildings on computer screens faster and with fewer mistakes. • Flexible Manufacturing Systems – a production facility that workers can quickly modify to manufacture different products. • Computer-Integrated Manufacturing – integrates robots, computers and other technologies to help workers design products, control machines, handle materials, and control the production function. Oversee the work of people and machinery to convert inputs (materials and resources) into finished goods and services. • Choose what goods or services to offer customers. • Convert original product ideas into final specifications. • Design the most efficient facilities to produce those products. • Process layout groups machinery and equipment according to their functions. • Facilitates production of a variety of nonstandard items in relatively small batches. • Product layout sets up production equipment along a productflow line, and the work in process moves along this line past workstations. • Efficiently produces large numbers of similar items. • A fixed-position layout places the product in one spot, and workers, materials, and equipment come to it. • Customer-oriented layout arranges facilities to enhance the interactions between customers and a service. Make, Buy, or Lease Decision • Choosing whether to manufacture a needed product or component in-house, purchase it from an outside supplier, or lease it. • Factors in the decision include cost, availability of reliable outside suppliers, and the need for confidentiality. Selection of Suppliers • Based on comparison of quality, prices, dependability of delivery, and services offered by competing companies. Inventory Control – Perpetual inventory – Vendor-managed inventory Just-in-Time Systems • Improving profits and return on investment by minimizing costs and eliminating waste through cutting inventory on hand. Materials Requirement Planning • Computer-based production planning system by which a firm can ensure that it has the correct materials for production. • Production control creates a well-defined set of procedures for coordinating people, materials, and machinery. 1) Planning 2) Routing 3) Scheduling 4) Dispatching 5) Follow-up Dispatching Manager instructs each department on what work to do and the time allowed for its completion. Follow-Up Employees and their supervisors spot problems in the production process and determine needed changes. • A good or service free of deficiencies. • Poor quality can account for 20% loss in revenue. • Benchmarking is the process of analyzing other firms’ best practices. • Quality control is measuring goods and services against established quality standards. • Many companies evaluate quality using the Six Sigma concept. – A company tries to make error-free products 99.9997% of the time, a tiny 3.4 errors per million opportunities. • International Organization for Standardization (ISO) - mission is to promote the development of standardized products to facilitate trade and cooperation across national borders. • Representatives from more than 146 nations. • ISO 9000 series of standards sets requirements for quality processes. • Nearly half a million ISO 9000 certificates have been awarded to companies around the world. • ISO 14000 series also sets standards for operations that minimize harm to the environment.
