Digital procurement solution is a critical tool when it comes to weapons systems delivery directly impacting force readiness. With digital procurement solution, all purchase orders will be sent over interface in the system so all parties are notified, ensuring delivery is completed immediately. At each stage your purchasing processes are streamlined, reducing logistics headaches and eliminate unnecessary paperwork.
Consider an aircraft manufacturing scenario in which company X produces tires, but subcontracts production of lug-nuts to company Y . In order to build a single system to automate certain parts of production/delivery process, the internal behaviours of both companies X and Y must be modeled.
But both companies are likely to do not want to relinquish information and/or control to a system designer representing the other company. It is possible with just two companies involved, an agreement could be reached, but with several companies involved,
Multi-agent systems are necessary. The only feasible solution is to allow the group of companies to create their own agents that accurately represent their goals and interests. They must then be combined into multi-agent system focused on digital procurement.
Using agent models is not a new concept; however, digital procurement will address long-standing challenges associated with complexity, uncertainty, and rapid change in deploying components contributing to readiness levels of defense systems. By providing for more agile and responsive development, digital procurement supports organisational excellence and provides a foundation for mission success in the future.
DoD must assess digital approaches to acquisition and systems engineering, including its methods for the use of agent models, simulation results and tools that support acquisition/sustainment process so it is possible to stay ahead of readiness demands for new and upgraded weapons systems.
Markets represent process that maps potential buyers and potential sellers of a good to one another and optionally to a price at which a sale can take place. The goods traded in such a market are characteristics or options for characteristics. Each distinct good requires a separate market, and markets for different goods may have different protocols.
Applying multi-agent technique in multi-section flexible manufacturing system requires setting up dispatch rules, a distributed agent based system is implemented, assisting agents to choose suitable dispatch rules pertaining to dispatch region and also full-in dispatch of manufacturing system resolved through the agents cooperation.
Multi agent systems can be used for simulation and modeling of production process or supply chain, where they easily simulate an independence of involved parts. These tools can help to answer non-trivial tasks – how changes in single component will affect the production process or supply chain as a whole.
For the uninitiated readiness officer the procurement process can appear to be a simple, basic procedure: Locate needed goods. Pay. Receive purchased goods. Document transaction.
But like all important business functions, procurement is a layered, fluid business process with multiple moving parts so there are numerous stages in the procurement process.
In many organisations, purchasing-- more than any other business function, is tied to routine. There are usually only periodic negotiations with established networks of suppliers or sources.
But many purchasing team skills and outlooks were formed years ago in an era of relative stability, and they haven’t changed. Now no company can allow purchasing to lag behind other departments in acknowledging and adjusting to accelerated tech changes. Such an attitude is not only out-of-date but also costly.
Few companies today can allow purchasing to be managed in isolation from the other elements of their overall business systems. Greater integration, stronger cross-functional relations, and more top-management involvement are all necessary.
The company will realise these benefits only if it uses the systems effectively. It must foster consistent, cross-functional information flows and demands and induce line managers to supply the required metrics for the purchasing information system. One way to reduce instinctive resistance is to show them that most of the “new” metrics already exist and need only be recast in an appropriate format. Finally, management must make certain that any major new systems are user-friendly.
Progress toward effective supply management can only be gradual, and the company will have to surmount many obstacles to implementation along the way. But the rewards are well worth the effort. An attitude of “purchasing as usual” will make the company vulnerable to competitive pressure; but enhanced strategic awareness, greater flexibility, and stronger focus in the supply area can improve the supply security and lower the input costs of any industrial company.
Too often the purchasing department receives information on the companies business plans and objectives that is incomplete or improperly geared to the tasks and time horizons of strategic supply management. Purchasing executives are usually informed of major expansion and investment projects but often lack adequate operating information under some timelines.
Every facet of the purchasing organisation, from systems support to top-management style, will ultimately need to adapt to these requirements. Concrete changes in the organisation will be required to establish effective organisational relations, provide adequate systems support, and meet the new staff and skills requirements.
Some companies have already responded to the growing pressures. To ensure long-term availability of critical materials and components at competitive cost, many manufacturers must come to grips with the risks and complexities of virtually unlimited sourcing. Others that already source from many entities must learn to cope with uncertainties and supply or price disruptions on an unprecedented scale.
Instead of simply monitoring current developments, orgaisations must learn to make things happen to its own advantage. This calls for nothing less than a total change of perspective-- from purchasing as an operating function to supply management as a strategic goal.
To reduce the long-term risk of dependence on a single source, the company could search for alternative suppliers or materials or even consider backward integration to permit in-house production. On the other hand, if the company is stronger than the suppliers, it can spread volume over several suppliers, exploit price advantages, increase spot purchases, and reduce inventory levels.
Whenever a manufacturer must procure a volume of critical items competitively under complex conditions, supply management is relevant. The greater the uncertainty of supplier relationships, technological developments, and/or physical availability of those items, the more important supply management becomes.
On items where company roles in the supply market is secondary and suppliers are strong, the company must go on the defensive and start looking for material substitutes or new suppliers, ie diversify. It may have to increase spending on market research or supplier relations, or even consider backward integration through major investments in R&D or production capacities. In short, the company needs its supply options.
For supply items with neither major visible risks nor major benefits, a defensive posture would be over-conservative and costly. On the other hand, undue aggressiveness could damage supplier relations and lead to retaliation. In this case, a company should pursue a well-balanced intermediate strategy.
Usually, a company will find itself in different roles with respect to different items and suppliers. When it can bargain from a position of strength, it should press for preferential treatment. Bargaining from weakness, the company may have to offer inducements—longer-term contract obligations, for example, or higher prices—in order to ensure an adequate supply.
To what extent might cooperation with suppliers or even competitors strengthen long-term supply relationships or capitalise on shared resources? For example some industry sectors reach out to others for production of certain critical components that they could not produce cost-effectively on their own. If suppliers can be involved early in the design process better quality, lower cost, and “just in time” production is likely.
Potential risks are evident in the event of non-delivery or inadequate quality. The higher such costs and the greater the risk of incurring them, the less latitude the company has for rapidly shifting supply sources or delaying negotiations or contracts. These costs influence required inventory levels but they mainly affect production.
Changing a source of supply might, for example, make it necessary to modify the production process. In the case of materials for highly automated production processes, the costs of such modification could be prohibitive.
The relative importance of different criteria may vary with technological change or with shifts in industry sector competition. Careful definition of the criteria of both supplier and company strength is a prerequisite to accurate market assessments.
Supply and demand patterns can blow up on you virtually overnight. How can an organisation guard against disastrous supply interruptions and cope with changing fiscal outlooks and new opportunities brought on by new technologies? What capabilities will organisations need to sustain itself in the face of strong protectionist pressures? Almost every kind of unit will have to answer these questions.
New approaches to devise strategies gives you a simple but effective framework for collecting marketing metrics, forecasting future supply scenarios, and identifying available purchasing options as well as for developing individual supply strategies for critical items and materials.
Following this approach, all purchased materials or components are classified in terms of impact on bottom lines and supply risk. Next, the supply market for these materials is characterised. Then the overall strategic supply position is determined. Finally, it develops materials strategies and action plans.
Organisations must explore a range of supply scenarios in which it lays out its options for securing long-term supply and for exploiting short-term opportunities; clearly define respective risks, costs, returns, and strategic implications; and develop a preferred option with objectives, steps, responsibilities, and contingency measures laid out in detail for top management approval and implementation. The end product will be a set of systematically documented strategies for critical purchasing materials that specify the timing of and criteria for future action.
Supply risk is assessed in terms of availability, number of suppliers, competitive demand, make-or-buy opportunities, storage risks and substitution possibilities. Using these criteria, the company sorts out all its purchased items according to placement in categories such as strategic, bottleneck, leverage and non-critical groups.
How much risk is acceptable? Vendor mix, extent of contractual coverage, regional spread of supply sources, and availability of scarce materials all contribute to supply risk profile. An organisation can often take action to lessen unacceptable risk for example, meeting periodic annual materials requirements exclusively through long-term contracts may achieve substantial savings through the use of periodic scheduled agreements
Tasks, resources and schedule constraints drive the timeline of a project. The project schedule is initially created by having the tasks needed to deliver an output created and then, the duration needed to complete the task assuming that 100% effort is spent on doing that task and that all inputs to that task are available is calculated.
Supply chain design decomposition distinguishes objectives and means of supply line administration. Because it systematically relates means to objectives at different levels of abstraction, higher-level objectives can be made actionable step-by-step. Using a structured procedure, decomposition techniques can be utilised to develop a supply chain strategy that is in alignment with strategic goals of the organization.
We develop a decomposition method for the Time-Constrained Procurement Scheduling Problem with Proximity Resources. For proximity resources the resource units are ordered and the units assigned to a job have to be in close proximity.
On top of that resource proximity is not required by single jobs, but by job groups. As soon as a job of such a group starts, the resource units in close proximity are occupied, and they are not released before all jobs of that group are completed.
Developed decomposition methods separate the resource proximity assignment from the rest of the scheduling problem. Test results demonstrate the applicability of the decomposition method. Decomposition forms a first promising approach for procurement scheduling constraints with resource proximity and may form a good basis to develop more advanced tech.
Procurement is so dynamic it requires constant monitoring by Site Visit Executive in an organisation. There is always more to know so forecasts can be produced – all of which is a big responsibility.
So…what are the stages in the procurement process? What are those constantly developing pieces in procurement?
As Site Visit Executive learns/reads more about the actions of procurement teams it becomes obvious that each personnel team involved in procurement has a slightly different take on the stages in the procurement process.
Here we present solid list of the critical stages in the procurement process:
1. Need Recognition
This is a seemingly obvious step, but one that needs to be mentioned. Procurement departments must recognise a product is needed in order to purchase it. That product can be either a brand new item, or one that is being re-ordered.
2. Specific Need
Does your industry have specific requirements for various products? If that is the case in your field of service be sure you are up-to-date on those requirements and order accordingly.
3. Examine Supplier Options
Every business needs to determine where to get their goods. Some companies have an approved vendor’s list while others are still trying to determine who the best suppliers are. Once a supplier is chosen, companies should stick with that relationship and try to establish preferred pricing.
4. Price and Terms
Once a supplier is chosen, companies should stick with that relationship and try to establish preferred pricing and specific terms i.e. delivery.
5. Purchase Order
The purchase order is used as the formal contract used to buy the product. The purchase order outlines the price, specifications and terms and conditions of the product or service.
6. Delivery
The transfer of the purchase order via contact network interface
7. Expediting
This stage addresses the timeliness of the service or materials delivered. Delays constrain successful missions so purchase order must have expected delivery date information.
8. Receipt and inspection
Once delivered, the receiving field unit must inspect and, subsequently, accepts or rejects the product.
9. Approval and Payment
At this stage, the following updates must match when the seller wants payment – the invoice, the receiving document attached to the product, and the original purchase order. If a discrepancy is found, it must be resolved before payment is made.
10. Record Keeping
The receiving customer must keep good records. This means saving all relevant documents for every completed purchase.
