A hierarchical algorithm for the flexible job shop scheduling problem is described, based on the tabu search metaheuristic. Hierarchical strategies have been proposed in the literature for complex scheduling problems, and the tabu search metaheuristic, being able to cope with different memory levels, provides a natural background for the development of a hierarchical algorithm.

This introduction article attempts to present some major issues relating to the integration of process planning and production planning and control PPC for flexible manufacturing systems FMSs. The various types of flexibility to be planned and provided for in process planning and manufacturing are summarized in the article, as well as emerging conceptual frameworks for integration, along with their implementation requirements and problems. Distinctive elements that differentiate these frameworks, such as the extent of integration of process planning and PPC activities, number of alternative process plans, and the time at which numerical control programs are generated, are discussed, followed by a brief summary of the articles compiled for this special issue.

Production Planning & Control | Meaning | Objectives | Elements | Stages

By PlanetTogether. Production planning and control PPC is a term that combines two strategies: production planning and production control. In the manufacturing world, production planning and control are defined by four stages: Routing, Scheduling, Dispatching, and Follow-Up. The first two stages relate to production planning while the second two relate to production control.

The first stage of production planning is to determine the path of production from raw materials to finished goods. Here, you will determine the equipment, resources, materials and sequence to be used.

The second stage of production planning is to determine when operations are scheduled. Here, the goals may be to increase throughput, reduce lead time, or increase profits. Many strategies can be used to create the most efficient schedule. The third stage of production control starts when production is initiated. That is, when the scheduling plan is implemented, materials and work orders are released, and work is flowing down the production line. The fourth stage of production controls is to determine whether there are any bottlenecks or inefficiencies in the process.

Here, you can compare the predicted run hours and quantities with the actual values reported to determine whether processes can be improved. Time and Capacity Management are crucial factors to enhance the efficiency of the shop floor and of the business. These factors are directly associated with the second stage of production planning and control: Scheduling.

Knowing this, let's focus specifically on the scheduling stage and the different methods used to approach it:. Master Production Scheduling MPS is a scheduling strategy that dictates when and how much of each product is going to be produced based on criteria such as demand, capacity, and inventory availability.

It includes a plan for the production of certain products and defines resources, staffing, inventory, etc required for the allotted time period. It also sets the expectations of the revenue that the business is likely to generate. This type of scheduling fixes a time and a date to each operation in a continuous timeline rather than in time buckets. Each process can then be visualized in terms of its start time and completion time-frame.

The subsequent stages of production planning and control depend on this timeline. Scheduling looks to optimize the use of time in each step of the production process, from raw or intermediate materials to the delivery of the finished good to the customer. The goal is to maximize throughput output and on-time delivery within the constraints of equipment, labor, storage, and inventory capacity.

This usually involves maximizing the utilization of critical bottleneck resources by:. In order to schedule more efficiently, there are a variety of methodologies ans tools that planners can apply.

Proper use of scheduling methods results in enormous benefits for a manufacturing business. Failure to systematize this process can result in lost customers due to late delivery and excessive lead times. In addition, cash flow problems can arise due to delayed shipments, and stressful operating environments are created due to the chaotic and reactive management of resources and orders. Advanced Planning and Scheduling Softwares have become a must for modern-day manufacturing operations as customer demand for increased product assortment, fast delivery, and downward cost pressures become prevalent.

These systems help planners save time while providing greater agility in updating ever-changing priorities, production schedules, and inventory plans. The implementation of an Advanced Planning and Scheduling APS Software will take your manufacturing operations to the next level of production efficiency by taking advantage of the operational data you already possess in your ERP system.

LESSON 8 PRODUCTION PLANNING AND CONTROL

What is Production Planning? Production Planning is the process of aligning demand with manufacturing capacity to create production and procurement schedules for finished products and component materials. It tracks and makes a record of the manufacturing process flows, for example, the planned and actual costs. Also, goods movements from the conversion of raw material to semi-finished goods. Organization Structure in SAP PP In any live Production Planning module, locations of manufacturing plants and storage within the plants, should be available in the system. Importance of Plant and storage locations in Production Planning- All Production master data is created at Plant level.

Planning refers to deciding in advance what is to be done in future. A separate planning department is established in the organisation which is responsible for the preparation of policies and plans with regard to production to be undertaken in due course. While explaining the concept of scientific management, F. Taylor emphasised the need of separating planning function from the function of actual operation in an organisation. For successful implementation of production control, production planning is of utmost importance. The planning department prepares various charts, manuals production budgets etc.

The first stage of production planning is to determine the path of production from raw materials to finished goods. Here, you will determine the equipment, resources, materials and sequence to be used.

Routing may be defined as the selection of path which each part of the product will follow while being transformed from raw materials to finished products. Path of the product will also give sequence of operation to be adopted while being manufactured. In other way, routing means determination of most advantageous path to be followed from department to department and machine to machine till raw material gets its final shape, which involves the following steps:. For effective production control of a well-managed industry with standard conditions, the routing plays an important role, i.

Routing is a document related to a manufactured product. It lists production operations stages , in the order in which the product is made. The goal of the Routing is primarily to provide grounds for scheduling the capacity of production resources, e. What a Routing is not: the technical instruction for building the product. In general, it's often a good idea to strive towards simplification and generalization when defining the Routing. Each line of the Routing represents one production operation at one stop - a machine or a work area - with an estimated time and costs it takes at that stop. The example above tells us that setting up the assembly area takes 30 minutes of work after which every table will be assembled with 12 minutes on average.

Scheduling is the process of arranging, controlling and optimizing work and workloads in a production process or manufacturing process. Scheduling is used to allocate plant and machinery resources, plan human resources, plan production processes and purchase materials. It is an important tool for manufacturing and engineering , where it can have a major impact on the productivity of a process. In manufacturing, the purpose of scheduling is to minimize the production time and costs, by telling a production facility when to make, with which staff, and on which equipment. But it's an academic purpose [ disputed — discuss ]. From a business point of view, the first priority purpose is to keep the customer's due date [ citation needed ].

Не нужно было так резко с ней говорить. Но у него не выдержали нервы. Он слишком долго говорил ей полуправду: просто есть вещи, о которых она ничего не знала, и он молил Бога, чтобы не узнала. - Прости меня, - сказал он, стараясь говорить как можно мягче.  - Расскажи, что с тобой случилось. Сьюзан отвернулась. - Не имеет значения.

Стратмор повернулся и с удивлением увидел Хейла. Сьюзан поняла, в чем дело: все это время Хейл вел себя тихо, подозрительно тихо, поскольку отлично знал, что нет такой диагностики, в которой использовалась бы цепная мутация, тем более такая, которая занимала ТРАНСТЕКСТ уже восемнадцать часов. Хейл не проронил ни слова. Казалось, вспыхнувшая на его глазах перепалка абсолютно его не касается. Очевидно, Стратмор вдруг задумался: .
