9 Supportability & Serviceability9 Elements of Support Continued … Support Equipment: Tools, condition monitoring, diagnostic, checkout, special test, calibration equipments etc. Computer Resources: Software necessary to support scheduled and unscheduled maintenance. Packaging, handling, storage, and transportation: Special provisions, containers and supplies necessary.

10 Supportability & Serviceability10 Elements of Support Continued … Maintenance Facilities : Includes facilities to support all the scheduled and unscheduled maintenance actions at all the levels. Technical data, information systems, database structure: Includes system installations, checkout procedure, operating and maintenance instructions, modification instructions etc.

11 Supportability & Serviceability11 Measure of Supportability Supply Chain Factors are Capability: The ability to accomplish all of the functions required. Availability: The ability to respond to any, or all, of the requirements at any point in time when needed. Quality: The process responsiveness in terms of stated customer objectives.

12 Supportability & Serviceability12 Transportation Measures Factors for evaluating the effectiveness of transportation are Transportation routes Transportation capacity or capability Transportation time Transportation cost

13 Supportability & Serviceability13 Transportation Measures Continued … Figure 15.5 The various forms of transportation. Rail transportation Pipeline transportation Highway transportation Water transportation Air transportation Rail-truck (piggyback) Trailer-on-flatcar Container-on-flatcar Truck-water (fishyback) Roll-on/roll-off Container-on-ship Air-truck Truck-on-aircraft Container-on-aircraft Rail-water Train-on-ship Container-on-ship

14 Supportability & Serviceability14 Packaging Measures Availability: transportation capability will be available when required. Reliability: it will complete its mission as planned. Time: transport a product from on point to another. Cost: the cost of transportation or per one-way trip.

15 Supportability & Serviceability15 Packaging Measures Continued … Maintainability: applicable transportation capability can be required within specified time and resources in the event of a failure. Life-cycle cost (LCC): the cost of a given transportation capability for a designated period of time.

16 Supportability & Serviceability16 Warehousing and Distribution Measure The basic functions of warehousing are Movement Storage Information transfer

17 Supportability & Serviceability17 Warehousing and Distribution Measure Continued … The movement function: Receiving: the unloading of goods and products from an inbound carrier. Transfer: the physical movement of products into the warehouse for storage. Order picking: the selection of products from storage in response to customer orders.

18 Supportability & Serviceability18 Warehousing and Distribution Measure Continued … Cross-docking: the movement of products directly from the inbound receiving dock to the outbound shipping dock. Shipping: the packing, loading on an outbound carrier, and shipment of products to the desired customer destinations.

19 Supportability & Serviceability19 Types of Warehouses Private & Public warehouses General merchandise warehouses Commodity warehouses Bulk-storage warehouses Bonded warehouses Temperature-controlled warehouses Houshold goods warehouses

20 Supportability & Serviceability20 The metrics in Warehousing Time that it takes to ship a product Cost of product shipment – from storage to customer Cost of storage Percentage of space utilization Volume of product handled

21 Supportability & Serviceability21 Spares, repair parts and related inventory factors The inventories associated should be able to supply spare parts for unscheduled as well as scheduled maintenance actions The required inventory of spares depends on system maintenance concept and specific type and quantities are identified for each level of maintenance

22 Supportability & Serviceability22 Factors affecting quantity of spares Spare and repair parts covering actual item replacements occurring as a result of corrective & preventive maintenance Additional stock level of spares to compensate for repairable items in the process of undergoing maintenance

23 Supportability & Serviceability23 Factors affecting quantity of spares continued…….. Additional stock level of spares to compensate for the procurement lead times for item acquisition Additional Stock level of spares to compensate for the condemnation of scrap age or repairable items

24 Supportability & Serviceability24 Inventory system considerations Too much inventory to meet all demands leads to increased cost of maintaining the inventory Lack of appropriate inventory will lead to stock depletion and the system not being operational leading to higher costs Optimum balance between inventory on hand, procurement frequency and procurement quantity is needed

25 Supportability & Serviceability25 General deterministic inventory system geometry Operating level Peak Inventory Safety stock Periods of time, days Quantity of items in stock Consumption Order Point Receipts, Q Procurement lead time Reorder cycle Zero stock

26 Supportability & Serviceability26 Economic Order Quantity (EOQ) See Pages 257-263 Q* is called EOQ

27 Supportability & Serviceability27 Design review and evaluation Design reviews are done to ensure 1.Prime-mission related elements are designed to be supportable in an effective and efficient manner 2.Design of logistics and maintenance support infrastructure adequately responds in fulfilling all system requirements

28 Supportability & Serviceability28 Design review and evaluation continued……. 3. If requirements are met, the design is approved and the program enters into the next phase 4.If requirements are not met,the appropriate changes are initiated for corrective action
