5 Production Operations in SCM
The Role of Production Operations Manufacturing and service production supplies an economic utility called form utility. Effective production operations are supported by and support the supply chain. Supply chain tradeoffs must be understood and made. Production Modes Make to stock vs. Make to order No two processes are organized exactly alike or perform to the same level. Make-to-order methods are more complex, more labor intensive, and require longer lead time than the make-to-stock, mass-production-oriented operations Process functionality helps the success of an organization.

6 Production Tradeoffs Economies of scope Changing customer demand
The Role of Production Operations in SCM, continued Production Tradeoffs Economies of scope The capability of being able to produce a range of products (product mix) Changing customer demand To be met by efficient production runs for a wide variety of products in low volume. Tradeoff decisions among production methods Based on good understanding of mfg. processes for goods and their costs Production and supply chain costs Which vary among make-to-stock, assemble-to-order, and build-to-order products.

8 Production Challenges
The Role of Production Operations in SCM, continued Production Challenges Intensified competition, more demanding customers, and relentless pressure for efficiency as well as adaptability. Competitive pressures for many established (and focused) manufacturers and service providers (OEMs and ODMs) (End) customers’ demand for choice and rapidly changing tastes.

9 Operations Strategies and Planning
Production (operation) strategies Focus on waste reduction, operation efficiency, and scale-ability. Use push-based strategies for immediate delivery of off-the-shelf, low-cost, standardized goods. Use pull-based systems to coordinate production and distribution with actual customer demand. Apply lean production concepts to minimize material flow time, by having materials arriving at the needed location just in time for processing and rapidly flowing them through the production system.

12 Production Strategies, continued
Operations Strategies and Planning, continued Production Strategies, continued Machine flexibility General purpose machines and equipment staffed by cross-trained workers provide the ability to produce different types of products Routing flexibility Provides managers with a choice between machines for a part’s next operation Offshoring Activity be relocated to a contract manufacturer in another country Adaptive manufacturing Provides companies with the ability to replace planning and replanning with execution based on real-time demand

13 Production Planning Long-range plans Medium-range plans
Operations Strategies and Planning, continued Production Planning Long-range plans Covering a year or more, focus on major decisions regarding capacity and aggregate production plans Medium-range plans Span 6 to 18 months and involve tactical decisions regarding employment levels and similar issues Short-range plans Ranging from a few days to a few weeks

15 Production Planning, continued
Operations Strategies and Planning, continued Production Planning, continued Resource requirements planning (RRP) Long-run, macro-level planning tool Rough-cut capacity plan (RCCP) Checks the feasibility of the master production schedule Capacity requirements planning (CRP) Checks the feasibility of the materials requirement plan Aggregate production plan (APP) Long-range materials plan that translates annual business plans, marketing plans into production plan Master production schedule (MPS) Medium-range plan that is more detailed than the APP

16 Production Execution Decisions
Assembly Processes (MTS), make to order (ATO), assemble-to-order (BTO), build-to-order (ETO), engineer-to-order Production Process Layout Facility layout Involves the arrangement of machines, storage areas, and other resources within the four walls of a manufacturing or an assembly facility.

17 Production Process Layout, continued
Production Execution Decisions, continued Production Process Layout, continued Successful layout is one that does the following: Reduces bottlenecks in moving people or materials Minimizes materials-handling costs Reduces hazards to personnel Utilizes labor efficiently Increases morale and ease of supervision Utilizes available space effectively and efficiently Provides flexibility Facilitates coordination and face-to-face communication Fixed location (project) layout Fixed location layout where the product remains in place for the duration of production Process layout (based on workcenter) Process-focused layout that groups together similar equipment or functions

18 Production Process Layout, continued
Production Execution Decisions, continued Production Process Layout, continued Manufacturing cell (cellular manufacturing) Process-focused layout that dedicates production areas to a narrow range of products that are similar in processing requirements Continuous (process) line Similar to assembly lines, with product flowing through a predetermined sequence of stops. Assembly line Product-focused layout in which machines and workers are arranged according to the progressive sequence of operations

20 Packaging Design issues can affect labor and facility efficiency.
Production Execution Decisions, continued Packaging Design issues can affect labor and facility efficiency. Can provide another level of product differentiation. Design impacts ability to use space and equipment. Ease of handling during materials handling and transportation. Protecting the goods in the package.

21 Production Metrics Total cost
All money spent on manufacturing must be summarized and the total compared to the previous period. Quality This may vary by company but it must focus on quality from the perspective of the customer. Total Cycle Time Total cycle time is a measure of manufacturing performance that is calculated by studying major purchased components and determining the total days on hand of each one.

22 Production Metrics, continued
Safety The standard metrics of accident/incident frequency, severity, and cost are important to monitor, with continuous improvement (i.e., reduction) as the goal. Delivery performance Is the percentage of customer orders shipped when the customer requested them to be shipped.

23 Production Technology
Manufacturing Execution Systems (MES) Central software used to monitor and control production operations. Linked to other enterprise tools like ERP systems, PLM tools, and scheduling and planning systems.

25 Summary Production operations include all activities and processes involved in changing the composition of a good or service—component fabrication, product assembly, and service request execution—for the purpose of creating form utility. Numerous tradeoffs must be made regarding production: volume versus variety, responsiveness or efficiency, make or outsource, and focusing on a limited number of competitive dimensions. Intensified competition, more demanding customers, and relentless pressure for efficiency as well as adaptability are driving significant changes across many manufacturing industry settings.

26 Summary, continued There have been significant development and shifts in production strategy. Organizations have advanced from forecast-driven mass production to demand-driven lean, flexible, and adaptive approaches. Capacity planning and materials planning are used to balance inputs, capacity (resources), and outputs so that customer demand can be fulfilled without creating waste. Most manufacturers use a combination of four production methods—make-to-stock, assemble-to-order, build-to-order, and engineer-to-order—to satisfy demand for their products. Within the make-to-order method, companies can leverage assemble-to-order, build-to-order, or engineer-to-order options, based on product complexity and weakness.

27 Summary, continued Facility layout involves the arrangement of machines, storage areas, and other resources within the four walls of a manufacturing or an assembly facility. Facility layout is influenced by the product characteristics, production strategy, and assembly process employed by the organization. Packaging plays important roles in the smooth transfer of finished goods from the plant to the distribution center and customer locations. Sustainability is a key consideration in packaging selection, and companies are turning to recyclable and reusable materials for exterior and interior packaging. Production KPIs must be linked to corporate goals and objectives, customer requirements, and overall performance of the production operation.

28 Summary, continued Critical production KPIs address total cost, total cycle time, delivery performance, quality, and safety. Manufacturing execution software solutions (systems) improve an organization’s ability to manage production operations and make them more responsive to disruptions, challenges, and changing marketplace conditions.
