Session 3: Cost Centers, Work Centers and Routings
Description of a manufacturing process Routings describe the manufacturing process to elaborate a product with its direct components This process requires often several steps (or operations) For each operation, one specifies which resource(s) is/are required the times to complete the operation Time to prepare the resource (set-up time or change-over time) Run time (time to perform the operation on one single part)
Routing = steps of the manufacturing process Routings - Definition M 1 Routing = steps of the manufacturing process M 2 Op. 010 Op. 020 Op. 030 Op. 040 Manuf. Product Px S / A Materials, components, fabricated parts and sub-assemblies

Session 4: Sales and Operations Plan
Sales and Operations Plans Can be stated as follows: Given a set of (usually monthly) forecasts of demand for a family of products (output), what should be specified for each period in terms of: Size of work force Rate of production Quantity shipped Establish a production plan: Minimizing the expected total costs or maximizing the margin over a given planning interval (6 to 24 months)
S&OP Goals Meet demand Balance projected workloads and resource capacities Meet inventory policy Minimize total cost (or maximize margin): Labor Inventory Plant and Equipment Subcontracting
S&OP Strategies Pure Strategies: 1. Chase strategy (change capacity) Change inventory levels Vary work force size by hiring or layoffs Vary production capacity thru overtime or idle time Subcontracting, part-time workers PRODUCTION = DEMAND 2. Level Strategy (anticipate demand) Constant work force Inventory builds up in slack period and backlog in high demand period Influence demand CONSTANT PRODUCTION
Pure Strategies Demand Demand Production Production Production = demand "Chase Strategy" Inventory Constant production Creation of inventories "Level Strategy"
A compromise strategy Compromise Strategy Combines the two previous options Based on both quantitative and qualitative factors An attempt to obtain the minimal overall cost which is a function of the costs structure Demand Production
Costs involved Base production costs (internal production and contracting) Costs of altering resource capacities Cost of over capacity utilization: Ex: overtime, external warehousing Inventory caring costs Shortage costs (or backlog costs)

Session 6: Material Requirements Planning (MRP)
Calculation of quantities to make and to source General principle: Materials Requirements Planning (MRP) Alternate method: Managing inventories La gestion sur stock de type “mini-maxi” est très peu utilsée sauf pour les articles de faible valeur comme les consommables ex : film étirables, huile de coupe ...
MRP Principle It starts with end-items (level 0) to generate quantities of immediate components (level 1) using the BOM. These are called gross requirements By taking into account the existing inventories, it computes the net requirements at this level = Gross requirements – Inventory on hand + Inventory desired level (safety stock) Future requirements are eventually regrouped (lot sizing) Similarly, all other levels are analyzed To position the requirements in time, it takes into account the production/procurement lead times of the items
MRP Principle Level 0 : Finished goods Level 1 : Sub-assemblies Master Schedule Level 0 : Finished goods FG Inventory and assembly WIP Finished Good Net Requirements Finished Good Assembly Orders Level 1 : Sub-assemblies Finished Good BOM Sub-assembly Gross Requirements Sub-assembly inventory and manufacturing WIP Sub-assembly net requirements Sub-assembly Manufacturing Orders Level 2 : Parts Sub-assembly BOM Part Gross Requirements Part Inventory and fabrication WIP Part Net Requirements Part Fabrication orders La procédure de planification se déroulera en deux phases : - niveau MPS (produits finis) - validation manuelle des ordres proposés - niveau MRP (tous les autres articles) Part BOM Level 3 : Materials Material Gross Requirements Material Inventory and open purchase orders Material Net Requirements Purchase Requisitions
Taking into account the production lead time Parent Item Release Date Parent Item Requirement Date Manufacturing Lead Time Date of component requirements To determine the release dates (for the parts to be produced) and those of the purchase orders (for the parts to be purchased), one must take into account the lead time required to obtain the parts (expressed in days). For purchased parts, the lead time is the Delivery Lead Time of the supplier For the parts produced internally, it is the time required to complete all the production stages of a batch of products. This time is defined in the routings.
Taking into account the procurement lead time (for purchased items) Material requirement date Date of purchase order issue Procurement lead time Specifies in days on the item window
Lot-Sizing Decisions MRP calculates net requirements and tries to optimize orders Avoid creating too many work or requisition orders in a short period of time Thus reduce the number of production orders releases or purchase orders which generate fixes costs (clerical work, changeover time, transportation, …) Main Techniques: Lot for lot Economic Order Quantity (EOQ) Part Period Balancing … Disadvantages : they increase the levels of inventories (because a requirement is anticipated)
Item Management parameters Reorder policy and Lot sizing rule define the way the item will be planned The Lead Time specifies the number of days normally required to get items from a vendor (purchased items) from the plant (manufactured items)
Item Management Parameters Access: Planning Menu, Item Reorder Policy Option 1 - Select the Reorder policy 2 - Select the lot sizing rule 3- Specify the production lead time

The Detailed Scheduling Function The problem On a short horizon (1 day to 1 month) We assume that the capacity of each work center is balanced with the work load generated by the work orders We have the list of work orders to be manufactured and the description of the operations to be performed Work Centers Standard Times Due dates
Detailed Scheduling Objectives Prepare a realistic work plan Manage the priorities for executing the work orders In order to Provide the workshops a detailed planning of the work to be performed on each machine
Possible objectives Meet the due dates for each work order Additional objectives: Maximize capacity machine utilization (specially for bottleneck work centers) Minimize WIP value (financial objective) Maintain some flexibility (commercial objective) Multiples objectives and partially contradictory
Detailed Scheduling Methods Scheduling Work Order per Work Order Forward scheduling Backward scheduling Choice of the loading priority Scheduling by sequencing rules Choice of a priority rule
Scheduling per work order Centralized system Work of the machine Gantt chart Forward or backward loading Work order per work order (all the operations of a work order are loaded at one time) The results depends on the priority of work orders Becomes wrong if real work differs from planned work due to unexpected event
