Level capacity strategy aggregate planning-With a beginning annual inventory of 600 and an ending annual inventory of 600, which set of values are correct for a Level Capacity aggregate planning strategy within Solution andChapter 13 Aggregate Planning 13 1 Menu About us;
Intermediate range capacity planning, Aggregate Capacity The process of planning and managing the overall capacity of an organization's resources Level Capacity Strategy Pure Maintaining a steady rate of regular time output while meeting variations in demand by a combination of opinionWhen using a "level capacity strategy" or "level production strategy" in aggregate planning, variations in demand are met by using which of the following options?Aggregate Planning • Aggregate planning is a part of larger production planning system;
Strategic Capacity Planning Aggregate Planning Long Range Medium Range Short Range How much & when to produce Aggregate Production Planning/ Four General Strategic Plans 1 Level – constant workforce/production level – fluctuating inventory levels 2 Chase – production and manpower fluctuate 3Aggregate planning is capacity planning for a the long range b the intermediate range c the short range d typically one to three months e typically one or more years B The main disadvantage (s) of informal techniques used for aggregate planning is (are) aAs Mixed Strategies Demand and Capacity Options Demand Options The four common demand options primarily focus on market aspects apart from backorders which is strictly operational management in nature The operations manager should know all four demand options but should be more interested in back order option
Chapter 7 Capacity Planning and Management Learning Outcomes After reading this chapter you should be able to • Define and measure capacity and appreciate the factors that influence it • Assess the difficulties of matching capacity to demand • Evaluate and apply the different strategies for matching capacity with demand in the short,The use of a level strategy means that a company will produce at a constant rate regardless of the demand level In companies that produce to stock, this means that finished goods inventory levels will grow during low demand periods and decrease during high demand periodsA level strategy seeks to produce an aggregate plan that maintains a steady production rate and a steady employment level ?
The primary difference among the three strategies is the lever, that is, the parameter that is manipulated to achieve equality of supply and demand over the aggregate planning period The first chase strategy uses capacity, in the form of machine or personnel capacity, as the leverHowever, it is feasible to hire or lay off workers, increase or reduce the work week,Capacity and Aggregate Planning Aggregate Planning The process
Taking plans from the aggregate level, disaggregate planning generates a general plan of action that will help the firm prepare for upcoming production The WIP/quota setting problem decides the quantity of work in process or periodic production quotas according to aggregate plan and capacity's characteristics (eg, setup time, changeover time among batches, productionI varying output during regular time without changing workforce size (for example, using overtime) II Varying output during regular time by changing workforce size IIIRole of Aggregate Planning in a Supply Chain Basic Assumptions – Capacity has a cost – Lead times are greater than zero Aggregate planning – Is the process by which a company determines levels of capacity, production, subcontracting, inventory, stockouts, and pricing over a specified time horizon – goal is to maximize profit Or, if
Aggregate production planning (APP) determines the resource capacity a firm will need to meet its demand over an intermediate time horizonsix to twelve months in the future Within this time frame, it is usually not feasible to increase capacity by building new facilities or purchasing new equipment; Level Strategy • Level strategy is a strategy the firm maintains a constant capacity over a period of time irrespective of the fluctuations in demand • This strategy is used when the skill level, training required, or the cost of hiring people and terminating them is high Demand Units Time Production 7 8 The aggregate planning that we are going to carry out will among other things attempt to match the level of bike supply to demand It is going to determine the required quantities and the timing of inputs as well as outputs There will also be making decisions on production, inventory, staffing and backorder levels
Maximize utilization of plant and equipment Aggregate Production Planning (APP) Operations Managers try to determine the best way to meet forecasted demand by adjusting various capacity Aggregate Planning balancing demand/capacity Strategies for meeting uneven supply & demand Level capacity maintain a level (steady rate) of production Capacity planning is a strategic process whereby a company determines what level of capacity it will need to satisfy the level of demand forThe Extremes Level Chase Strategy Strategy Production Production rate equals is constant demand Basic Aggregate Planning Strategies for Meeting Demand Level capacity strategy • Keeping work force constant and maintaining a steady rate of regulartime output while meeting variations in demand by a combination of options (such as using inventories overtimeparttime

Steps involved in aggregate capacity management Understanding the aggregate demand and supply for a specific period of time Preparation of suitable plans and contingency plans for situations where the demand levels might fluctuate Finalizing an appropriate planAggregate planning strategies Implementing aggregate planning in practice 2 Role of Aggregate Planning Capacity has a cost, lead times are greater than zero Atli Aggregate planning process by which a company determines levels of capacity, production, subcontracting, inventory, stockouts, Aggregate planning is a marketing activity that does an aggregate plan for the production process, in advance of 6 to 18 months, to give an idea to management as to what quantity of materials and other resources are to be procured and when, so that the total cost of operations of the organization is kept to the minimum over that period
Aggregate planning is a type of medium range capacity planning that typically covers a 3 to 18 month period of time Used in a manufacturing environment and determines overall output levels planned as well as appropriate resource Reactive Aggregate Planning Strategy The reactive aggregate planning strategy helps in managing fluctuating project demands through different plans The reactive aggregate planning strategy creates changes in the capacity to match with the changing demand Here are options widely used when developing the reactive aggregate planning strategyAggregate Planning Strategies Tradeoff between capacity, inventory, backlog/lost sales Chase strategy – using capacity as the lever Time flexibility from workforce or capacity strategy – using utilization as the lever Level strategy – using inventory as the lever Tailored or hybrid strategy – a combination of strategies

• Different aggregate planning strategies & options for changing demand and/or capacity in aggregate plans • Develop aggregate plans, calculate associated costs, and evaluate the plan in terms of operations, marketing, finance, and human resources • Differences between aggregate plans for service and manufacturing companiesLevel scheduling maintains a constant output rate, production rate, or workforce level over the planning horizon In other words, a level strategy is an aggregate plan in which production is uniform from period to period Firms like Toyota and Nissan keep production at uniform levels and may (1) let the finished goods inventory go up or down toLevel capacity strategy When an organization adopts the level capacity strategy then it manufactures at a constant output rate It does not consider any fluctuation or change in the level of demand This may lead to stockpiling or holding of inventory in high quantity, when there is a decrease in the demand level
Inputs and Outputs to Aggregate Production Planning Aggregate Production Planning Demand Forecasts Company Policies Financial Constraints Strategic Objectives Capacity Constraints Size of Workforce Production per month (in units or $) Inventory Levels Units or dollars subcontracted, back ordered, or lost 18Therefore understanding the interfaces between plan and several internal and external factors is essential for effective aggregate planning 8 Capacity planning is defined as a method to gauge the production capacity needed to meet the changing product demands of an organization Two terms of design capacity and effective capacity are used extensively in the context of capacity planning The first is the maximum work that is completed in a specific period by an organization, and the latter is the
Example 1 Level strategy • Each period is hours • From the beginning manager has 10 parttime workers • She wants to minimize undertime in this level strategy • Maximize overtime in order to minimize undertime • Overtime can not exceed percent of the regular time (that is 4 hour) in any period •
