One of the most critical tasks for any manufacturing organization is balancing assets (e.g., capacity, materials, people) with demand. Planners must determine how best to meet the demand given (1) available assets, (2) the production and distribution network, and (3) business policies.
Typically, organizations that automate supply planning can achieve a number of key benefits:
With three supply planning approaches, Arkieva can help your organization reach these benefits, too. The approaches are:
Key Features
Within each approach there are a number of variations. Determining which approach and which variation works best for a firm at a point in time is always situation specific.
The Arkieva Supply Planner is a comprehensive optimization tool for keeping supply aligned with corporate objectives in the face of change. Creating an optimal plan to meet demand is integral to managing your supply chain effectively. Our tool can generate a sustainable reduction in inventories up to 20% across the network through less costly overtime, increased throughput, and fewer setups.
Arkieva models the internal and external supply chain across the global enterprise; multi-site, multi-user, and enterprise-wide. Our tool synchronizes material and capacity allocation with production and planned purchases, optimizing operations with true customer demand. The ability to quickly re-plan provides increased flexibility in manufacturing.
The Supply Planner allows creation, of multiple what-if scenarios, varying factors such as demand and capacity, anticipating potential external threats like strikes, etc.
Arkieva Supply Planner also provides desktop capabilities for operations managers to promptly handle constantly evolving situations and still preserve both margins and customer service. The familiar Excel-like interface makes it easy to enter or review capacity, costs, and other required data used for optimization. It can easily generate supply/demand reports, including side-by-side, visual comparison of what-if scenarios.
Flexibility and rapid turnaround are essential in a changing marketplace, whether evaluating new growth opportunities or managing costs. Arkieva Supply Planner offers the ability to quickly create profit-driven supply scenarios for contingency planning, in a sandbox environment, before committing resources.
If you have many products which can be made with different recipes and on different facilities, how do you decide where and how to make them? Different manufacturing methods may have different yields, or some products can be produced at a higher rate on certain machines. Usually, each product will have a preferred manufacturing method, but often ingredients are scarce, or capacity is limited, preventing you from making all products in a preferred way. This means you will need to choose which products need to utilize secondary recipes in order to satisfy the demand. Different choices may lead to significant cost differences, so it’s important to plan all the products jointly to minimize the cost while meeting demand promptly.
An optimization model optimization model can be used to determine how best to manufacture all the products with the given resources, minimizing the sum of all costs, including unmet demand, cost of production and inventory cost. The different recipes are prioritized, but it is free to choose a secondary recipe if it lowers overall cost. Because it can compute automatically the amount of capacity used by each recipe, it stays within the limited number of available hours. An optimization model can even look ahead to future periods when capacity might be low and build inventory to meet future demand which could not otherwise be satisfied. By considering all the possible supply options, it can better utilize resources by developing a global plan.
A company must make decisions each month on the best way to satisfy demand when it has many products manufactured with different BOMs. An optimization model can be a valuable tool in getting the most out of resources while keeping costs low and customer service levels high.
Balancing the many different costs of manufacturing is a difficult task when you consider the almost limitless possibilities of the ‘what,’ ‘how,’ and ‘where’ to produce a product. Manufacturing resources are limited both in capability and capacity, meaning many products contain a key ingredient with varying concentrations and the supply of those key ingredients also comes in different concentrations. Transportation costs, inventory limits, inventory costs and contractual considerations, such as “Take-or-Pay,” are also all key factors in deciding the manufacturing plan.
An optimization model can take all the restrictions on supply and capacity and find the best way to satisfy the demand. It takes into account the purities and costs of all input streams to find the best way to get output with the desired purity at the lowest cost. It can also take into consideration any contractual obligations. It balances all the costs and revenues simultaneously to come up with the best answer possible, within the given constraints. It also allows users to evaluate impacts of changing suppliers, adding new capacity or changing demand.
Satisfying the demand of customers with products of many different purities can be a complicated decision that can prove to be of very high value. An optimization tool provides a way to utilize all resources efficiently and in a cost-effective manner.
For businesses to be more profitable, they need to balance the costs of waste, manufacturing, and inventory, and come up with the best plan to satisfy their demand. There are many industries in which products are manufactured in large sizes that need to be cut down to smaller sizes which are then sold to customers; examples include paper, film, and glass. Often, industries cut their larger products into smaller sizes in many different ways and during the cutting process, it is always important to minimize the amount of product lost and maintain the productivity of resources. Some cutting patterns with very low waste may also take much longer to cut or cause major problems for material handling. And if semi-finished inventory is kept, it needs to be in sizes that can be cut efficiently.
An optimization model finds the combination of patterns that will produce the necessary number of each size with minimum cost. While minimizing waste is important, it would be a mistake to make it the sole component of the cost function. The goal should be to minimize total cost, which includes not only waste, but also resource usage and inventory. Some patterns with low waste may require longer setups and processing time. Even cutting strategies with the same waste may differ in how efficiently they can be cut. Unless the cost of using resources is considered, the plan is likely to be suboptimal.
It is also important to consider the cost of inventory. To keep waste loss low, it is common to produce extra of some sizes that fit well in a pattern. While this is fine if the extra will be usable and there is not too much inventory, the cost still needs to be considered. Many of the problems in cutting can be made a lot easier by having a size efficiently cut into smaller sizes. Planning should include the generation of the larger sizes, as well as the downstream pattern generation. Producing wider widths upstream may look more efficient, but may just translate into downstream waste. Production needs to be optimized across the whole process.
When part of a production process involves cutting larger sizes of products into smaller ones, the problem of how to do this, so waste is minimized while keeping productivity high is extremely important. Even a 1% reduction in waste can often mean substantial savings. An optimization tool can provide significant improvements in multiple aspects of these processes.
