1. Can OEE Target work in a network?
We have created OEE TARGET so that it can be executed anywhere. The user only needs the USB storage device it is distributed with. This allows us to maintain a good price and on the other hand allows the user to work freely without having to depend on the installations the IT (computer) departments may make. Nevertheless, Idasanet is a company with extensive experience in the design, development and implementation of network industrial applications. If your company is interested in installing OEE TARGET in a network, please indicate this in the comments of the offer request form in section "How to buy" of this web. We shall send you an estimate adapted to your needs.

2. Does it work under Windows 8? What are the requirements?
Yes, OEE TARGET is compatible with any version of Windows from XP SP3 or later.
You also need to have the following software installed:
Microsoft .NET Framework 4
Microsoft Access Database Engine 2010
Microsoft Report Viewer 2010

These programs are all freely distributed and you can download them clicking on the links. You can also find them on the USB storage device you will receive with your application


3. What difference is there between measuring the OEE indicator and calculating OEE Target?
El OEE (Overall Equipment Effectiveness) is a percentage ratio used to measure the productive effectiveness of industrial machinery.

OEE's advantage over other ratios is that it measures, in just one indicator, all the fundamental parameters in industrial production: availability, effectiveness and quality. Having an OEE of, for example, 40% means that out of 100 good parts that the machine could have produced, it has only produced 40.

It is said that it covers all the fundamental parameters, as from analysis of the three factors that make up the OEE it is possible to know if what is missing up to 100% has been lost due to availability (the machinery was stopped during a certain period of time), effectiveness (the machinery was operating below its total capacity) or quality (defective parts have been produced ).

OEE = Availability * Performance * Quality

6 Big losses are considered to measure the OEE:
1. Downtimes/Breakdowns.
2. Configuration and Adjustments.
3. Small Downtimes.
4. Speed losses.
5. Rejections due to Start-up.
6. Production rejections.

The OEE measurement is made directly, counting the parts that leave each machine in the production line, registering downtimes due to format changes, rejected parts, etc.

Establishing a goal for the OEE indicator is complicated. Executives are sometimes tempted to compare results of different lines. Sometimes magical numbers such as 85% (World Class) occur to them. Proposing a small improvement on the results of the previous year or month may seem adequate but is not enough. OEE TARGET allows calculating the value of the OEE indicator we can expect to obtain and it does this objectively.

OEE TARGET is not a measurement but rather the result of a calculation. OEE TARGET takes into account the composition of the production line, the mix of references to be manufactured and which materials will be used for this, the quantities of each product to be manufactured and the work systems implemented. All of the above to establish 3 coefficients that define the OEE TARGET.

OEE
ME, Maximum attainable OEE coefficient due to the complexity of the Equipment.

OEE
MP, Maximum attainable OEE coefficient due to the complexity of the Products.

OEE
MM, Maximum OEE coefficient attainable due to the impact of the adopted work Methodologies. And finally OEE TARGET that is the result of the three.

OEE
Target = OEEME x OEEMP x OEEMM

4. How does OEE Target calculate the complexity?

We will all agree that the more complex a line (the more equipment and operations necessary) the more breakdowns it will have, the more time it will take to commission it and possibly the more rejections (non-conforming products) it will generate.

In the same way we can reach the conclusion that manufacturing only one product reference is not the same as manufacturing 100 different references. Evidently downtimes due to changes in format, non-conforming products, lost time in commissioning will be longer the higher the number of references handled.

Well, all of this seems evident... But how much? How much does this influence the OEE obtained at the end?

With OEE TARGET we collect in an orderly fashion all the data of the lines establishing the "complexity" concept. Starting from the general factory data (site) we reach a sufficient level of detail that allows obtaining for each line three coefficients linked to three different complexities:

OEE TARGET establishes the OEE ME concept, Maximum attainable OEE coefficient due to the complexity of the Equipment. When we talk about complexity we are referring to the design of the production line as regards the machines and equipment that make it up and as regards the materials that are used for manufacturing.

The equipment are studied from the point of view of the operations they carry out and their MTTF/MTBT (Mean Time To Failure or Mean Time Between Failures) and the MTTR (Mean Time To Repair). This data is used to determine the maximum and minimum performance ratio of each production line for each equipment complexity. The equipment are also classified in 4 degrees of complexity: A, B, C and D depending on the number of materials they handle and the quality control systems they have.

The second parameter calculated is the OEE MP, Maximum attainable OEE coefficient due to the complexity of the Products In short, this coefficient is determined by the mix of references manufactured and the quantity of each one. Thus we can have a clear idea of the amount of changes of batch and format that we will have throughout a year. Furthermore, taking into account the types of materials handled in the manufacturing of each reference we will classify the changes of format according to their complexity. There is a big difference between a change of format implying only changing the final labelling and another type of change of format where practically all materials have to be removed to introduce materials of a different type...

Finally, the OEE MM, Maximum OEE coefficient attainable due to the impact of the adopted work Methodologies is calculated. The OEE TARGET software allows registering which are the established guidelines as regards work shifts, duration, cleaning, breaks, etc. The loss of availability of the facilities is calculated that determines the maximum performance we can obtain due to our way of working. We recommend carefully reading the OEE TARGET specifications.


5. 5. How can I get printed reports of OEE Target?
es, all the calculations can be printed in a summary report. A PDF file is generated that you can print, send by e-mail or just save in your file. You must have Microsoft Report Viewer 2010 installed to see the PDF reports Microsoft Report Viewer 2010.
