When you have a part this tool gives you multiple options with respect to that manufacturing feasibility. For example, if a sheet metal part can be manufactured using 5 processes this tool gives cost and it also helps to understand what will be challenged with machines and parts.
I found aPriori is a great tool that supports all stakeholders of any product lifecycle in the Design Development of Product Maintenance. Also found it as an excellent tool in the hands of a Designer to understand the impact of design on cost and identify design cost Issues and design rule violations early into the design phase. aPriori is also helping to understand the effect of alternate designs and processes.
Pros
Easy to understand algorithm.
In large databases, join and prune steps are easy to implement.
The resulting rules are intuitive and easy to communicate to an end user.
Cons
Dynamic itemset counting technique can add new candidate itemsets at any marked start point of the database during the scanning of the database.
The transaction reduction method reduces the number of transactions scanned in interactions. The transactions which do not contain frequent items are marked removed.
The sampling method picks a random sample from the database for frequent itemset. It may be possible to lose a global frequent itemset.
Likelihood to Recommend
From my experience aPriori is a classical algorithm in data mining. It is used for mining frequent itemsets and relevant association rules. Also, it is devised to operate on a database containing a lot of transactions, for instance, items brought by customers in a store. Whereas aPriori requires high computation if the itemsets are very large and the minimum support is kept very low and the entire database needs to be scanned.

We use aPriori for our product should-costing which can be further used for negotiation with our suppliers. We also use aPriori for our cost down/NPD projects so that we can evaluate the design changes with respect to cost. In our organization, we are the only ones using this tool and supporting all the segments.
Pros
Excellent cost model maturity level
Reliable data library for different regions
Precise should-cost have well-defined cost drivers
Spreadsheet report flexibility with cost insights
Cons
Cutting parameters and logic for milling process need to be reviewed and refined
Super-finishing processes need to be added
Likelihood to Recommend
aPriori is well suited for a sheet metal and plastic process group. In machining, it is somewhat good for the turning process but in the case of milling processes, aPriori needs to look seriously and come up with a refinement.
We can imagine and dream about a product that we like, but when it comes to cost we take a wild guess. Being more realistic about cost by considering all of the parameters is an essential feature required by any customer in modern days—this is being fulfilled by aPriori. It also creates transparency inside the organization and more realistic cost. Greater efficiency/faster with greater accuracy.
Pros
Creating Transparency
Greater efficiency/faster results
Greater accuracy
Cons
Need competent user
Likelihood to Recommend
In new product development, it is well suited to help show the cost of potential and early visibility to management.
We use aPriori to have the best parts with a fair price with the right process/supplier. It is great software for NPI and renegotiation tasks. We use the reports to get fair prices and to develop a high-efficiency process at our supplier base.
Pros
Cost reduction
Tooling costs
Parts cost
Source decision
Cons
NPI - quotation
Likelihood to Recommend
NPI is a must have since it is an area where the reports are helpful since we do not have that process in place. For current parts it is easier to decide on suppliers because we just moved to a similar process for suppliers, but it is also helpful to quantify the investments and the best process route.
The perfect scenario would be a machined piece with simple features and standard stock. Sheet metal without complex bends. Machining from a casting is a great example of the capabilities of the program and how well it can do it.
aPriori is used in our cost management team. We are support functions in our organization that are responsible for the cost analyses. Our analyses are used across the organization. The cost analyses used for value-based negotiations, New Product Development pricing, spend optimizations for suppliers, reverse engineering, and value tracking for various commodities etc., Processes are updated to maintain the maturity of the cost results we get from it.
Pros
Speed and capacity
Bulk costing
Detailed cost analysis involving complex geometries of parts
Cost insight design
Product Cost management support
Cons
Customization of the cost logic is tricky.
Full products costing & process involved in the proprietary parts are less or not available for costing
Sheet metal logics for costing may be improved.
Focus on Electronics Cost models
Electronics - Component Costings

On the fly costing is one of the good things aPriori has. Once the engineer does the design, he can check the cost immediately. So the cost avoidance part is very good. An engineer can optimize the design to cost. This helps to avoid engineering wasting time and supplier settlements will happen on time. The negotiations also will be very much fact based & supplier agreement happens faster.
aPriori helps us to clearly understand the cost structure and to establish the should cost models globally through our department. As it has the capability to calculate the cost directly from 3D models so we can have cost models for a wide range of configurations.
Pros
Fast cost calculation
Wide coverage of process group
Good frequency of data update
Cons
Sourcing
New product development

aPriori is well suited for organizations which has a demand in their cost structure.
<ul><li><b>Product Cost Management : </b></li></ul>At my organization we started product cost management three and half years ago, and I am responsible for all "cost down" related activities in the organization. We are also responsible for cost avoidance and target costing for the new products. we are all familiar with the tagline "Cost Before It Matters" and had a few workshops where we found the tool is very agile and able to cost using facts and data, which is critically important for survival in this fast moving-world and for being the best in the industry.
<b>aPriori</b> is essential in our department for activities such as:
<ul><li>Potential for current parts- Value- Base Negotiation [ Direct Savings from Current Suppliers]</li><li>Providing target cost for new products [ New Product Development]</li><li>Speed, innovation, capacity</li><li>Generating the Technical Ideas during the Supplier workshop , Idea Generation Workshops</li></ul><b>Business Problem:

Pros
Sheet Metal-Process Group, Transfer Die is at the Best, which gives detailed operation setup for the Parts as well as shows the number of parts in the Sheet i.e nested Loop thereby reducing the Scrap as well (Scrap Management)
Forging-Steel: Very good for for medium and complex medium Hot Forging type parts. Machine overhead data is very detailed where facts are used for the negotiation i.e Electricity Rate, Power, Labour Rate, Maintenance rate, etc.
Surface Treatment / Other Secondary Process such as powder coating, wet coat, electro plating: These all work well. We can also use masking options the treatment, In the event of of any leak tests or X-Ray inspections, we can add the process which will then account the pre/post operation time for the treatments
2-Model Machining: Machines and routing combinations are huge and can be used to determine the most economic way to produce these parts. We can also override to find the supplier methodology and cost. It gives very detailed information on the feed rate, speed rate, and power capacity.
Geometric Dimensioning and Tolerating (GD&T) can be added on the GCD's which will help detect the super finishing process, which is another advantage. In the current 2016 R2 SP, aPriori can detect it from the CAD Models
Design to Cost feature, provides the design engineers as well as cost engineers to understand the which feature take most cycle time and whether changing that feature reduces the complexity in machining thereby cycle time can be reduced
Cons
Investment Casting Model: We have a basic model where we have captured all the processes involved, but when logic is being missed in the same in process, we have to fine-tune it to make it as effective as other process groups.
Powder Metal technology: Similarly, we need more process setup options in order to provide more logic for manufacturing. It does have the basic manufacturing setup
Mass Volume Machining: Transfer machines, swiss lathes need to be incorporated for Mass and high-speed machining
Forging: Hollow Forging as well as forging of Non-Ferrous metal need to addressed as the Forging cost is too high

<b>Forging:</b>
<ul><li>Excellent for medium size and medium complex parts</li><li>Weight range: 2-50 kg</li><li>Material: Steel</li><li>Forging: Hot Forging</li></ul><b>Die Casting:</b>
<ul><li>Best with good routing and machine selection according to the die size and part size</li><li>Melting Model need very little logic</li><li>Separate components for Melting and Casting i.e. cost can be derived for each activity </li></ul><b>Machining of Casting/Forging:</b>
<ul><li>Process group is the best for machining</li><li>Many routings where we can play with activating the turning setup / setup axis activation</li><li>We can experiment with different Routing and aPriori tells us why it cannot be done and gives useful data for redesign </li><li>Gives all Machining parameters i.e machine name, feed rate, speed running, power capacity, etc.</li></ul><b>Surface Treatment:
</b><ul><li>We can use the Parts in the barrel or in rack for heat treatment</li><li>Masking can be done for painting parts</li></ul><b>Other Process:
</b><ul><li>Testing processes also available i.e. X-Ray test, leak test etc...</li></ul>Above all it is really great tool, and big thanks aPriori for enhancing the current technology and digitalization landscape!
aPriori is mostly used by two differents engineering development teams to know in real time the cost of a part/assembly/product. We have a costing simulation department who uses aPriori to give this feedback cost to the development team.
So, it helps in many ways:
<ul><li>Be quicker and more confident when we have a design decision to make for in-house development project</li><li>Give a fast quote to our customer in a build to print product</li><li>Remove the number of RFQ to our suppliers</li></ul>We are also starting to use aPriori to set our manufacturing rate
Pros
Give visibility to cost really quickly
Be able to benchmark other regions of the world or other process/equipment that can be used to do the same part
Easily visualize the Geometric Cost Drivers that are more important
GIve some hints on where to work to get the cost down
Cons
Be more easy to customize without that much IT knowledge
Give more hints on how to reduce cost
Be able to build customize report

[It's] very powerful and useful. It became a must-have/"cannot live without it anymore" [tool[ very quickly throughout all the company. We were at ease waiting 1 or 2 weeks to get a price/quote and now, when people wait more than a day, it's too long for them. So far, we only use 20% of the software and cannot wait to see what we will do with it in the future. It could more be more customizable.
