The Logistics Function
The elements of logistics make up the logisticfunction, which, although essential to cost-effectiveand efficient operation of the firm, has only inrecent times been identified as a separate activity,yet one that becomes meaningless if isolated.

Logistics in Product Development
• The primary thrust is two-fold
- Influence product design to ensure reliability, usability, safety, system
- Identify the Logistics resources to ensure supportability of the delivered product andcustomer support
• Logistics translates performance, user requirements and user experience into the operational, maintenance and support concepts
![Page 18: 1 Logistics Systems Engineering Logistics System Definitions NTU SY-521-N SMU SYS 7340 Dr. Jerrell T. Stracener, SAE Fellow](https://reader030.vdocuments.us/reader030/viewer/2022032707/56649e525503460f94b47b86/html5/thumbnails/18.jpg)

Logistics in Product Development - continued
• Logistics design criteria and guidelines are provided to design
• As the schedule progresses, maintenance andsupport requirements (scheduled and unscheduled)are determined
• Requirements for support equipment, spare parts,publications, training, facilities, personnel and skillsare established

Logistics Systems Engineering
Broadly defined, systems engineering is ‘the effective application of scientific and engineeringefforts to transform an operational need into a defined system configuration through the top-downiterative process of requirements definition, functional analysis, allocation, synthesis, designoptimization, test, and evaluation.’ The systemsengineering process, in its evolving of functionaldetail and design requirements, has as its goal theachievement of the proper balance between operational (i.e. performance), economic, andlogistics factors.

Current Emphasis on Logistics
• Increasingly, companies look at processes, insteadof functions to achieve competitive advantage
- Advanced planning software allowscompanies to achieve efficiencies in order-to-delivery processes- Companies try to emulate success of inventory replenishment strategies ofWal-Mart and other industry leaders
• International sourcing of goods required bettercoordination with suppliers and transportation providers to minimize costs

Current Emphasis on Logistics
• Time based competition and Just-in-Time production necessitates
- Better coordination between customersand suppliers- Improved flow of information- Reliable transportation
