This integration of functional areas of the company is not limited to domestic of the organization, it is necessary to interface with suppliers and customers to get a unique supply chain that includes all supply, production, distribution and sale.
1. Strategic Level : planning approach from a strategic perspective: that is, question the purpose and objectives to achieve with this process, with a long-term horizon.
long-term planning is characterized by treatment set of all processes of the supply chain with a unique time horizon and the same geographical area.
Such planning requires a very high degree of aggregation, both estimates of the demand and prices, costs and structure, provide structural changes that will affect the entire supply chain.
Get the coordination of different processes is the main task of information systems to perform integrated planning.
3. Operational level : realization of the plans in the short term,:
• Inventories.
• Distribution.
• Production.
• Supply.
• Transport.
II. Areas planning (inventories, demand, production, distribution)
The various functional areas of planning developed mainly tactical and operational levels and affect:
1. Inventory planning.
2. The distribution planning.
3. Production planning.
4. Supply planning.
5. Transport planning.
Features:
1. inventory planning.
Objective: The objective of inventory planning is to establish the optimal level of stocks, taking into account the level of service offered and the cost it represents.
Functions and required data: There are two key concepts to consider: a.
The safety stock level, can be determined according to a fixed amount or considering a few days of coverage or service level. B.
The dimensions of the lot.
Results: The result will be the level of stock required for each reference.
2. distribution planning. Objective
: The objective is to plan the size and number of shipments between the different points of the distribution network.
functionalities and data required: To make the planning of the distribution, you must: a.
Having defined both the different elements of the distribution network (production and distribution centers) and the types of transport to use between them. B.
Knowing the inventory level needed, after which applications will be issued shipments.
Results: Results obtained will be the source and destination of shipment, the type of transportation, the scheduled date and quantity to be transported.
3. production planning. Objective
: To identify possible deficiencies in production capacity in advance to provide an adequate response.
functionalities and data required: The production planning is developed taking into account the limited productive resources (machines and manpower).
This plan calculates the saturation level for a given period and, thus, apply solutions to balance the situation.
Results: The result will be a production plan in the medium term that will indicate the situations of saturation and will also supply needs.
4. supply planning.
Objective: The objective of supply planning is to provide a plan of aggregate orders to suppliers to meet the production plan.
functionality and data requirements: supply planning list of materials required for each product family. From of final demand will analyze the needs of each critical material and inventory status to generate, when appropriate, a planned order to the supplier.
Results:
5. transport planning.
Objective: The aim of transport planning is to optimize its capacity and ensure that supplies are suited to the requirements of the commodity.
functionality and data requirements: planning systems transport can automatically generate charges from a number of parameters in place (capacity, delivery times ...) depending on the priorities (products, dates ...) presets.
Results: The results we get are a series of planned shipments based on a minimum load with specific dates.
