What do ope and oee indicators mean?

Ope (Overall Process Effectiveness) is similar to OEE and is a tool to measure production efficiency. OEE is relatively common, with key equipment as the research object; OPE is more used to measure the overall efficiency of the whole production line or technological process mainly based on manual assembly.

OEE (Total Equipment Efficiency) is an independent measuring tool to show the ratio of actual production capacity to theoretical production capacity. Through the analysis of each sub-item of OEE model, it can accurately and clearly tell you how efficient the equipment is, how much loss there is in which part of production, and what improvement work you can do.

Although there are some differences between OEE and OPE in concept, the principle is the same. In a word, it is the ratio of time to make money and time to produce.

1. We are familiar with OPE or OEE, both of which are learned from lean production and TPM-related literature and lectures. But here we should give them an explanation. OEE and OPE have always been production indicators, not equipment management indicators.

2. Various digital suppliers expect to obtain values manually or automatically to identify these lost time. Actually, this is very difficult. The difficulty lies not in technology, but in management. If this idea is determined, there will be data errors and unfairness in management. Instinctively speaking, no one wants to record these lost times more. The more accurate the record, the more likely it is to be evaluated.

We calculate the standard working hours of this line, and according to the start time and end time of production and the number of qualified products, we can get an OEE or OPE that can't be faked. Namely: OEE/OPE= = (standard working hours of single piece × quantity of qualified products)/production time.

Calculation method of oee

1. When calculating the ocoee, you can first multiply the time productivity by the performance productivity, and then multiply it by the yield to get the result.

2.OEE means comprehensive equipment efficiency or overall equipment efficiency. Generally speaking, each production equipment has its own theoretical production capacity. If we want to ensure the theoretical production capacity of the equipment, we must ensure that there is no interference and other losses during this period. OEE is an independent measurement tool to express the ratio of actual production capacity to theoretical production capacity.

3. OEE is a simple and practical production management tool, which has been widely used by European and American manufacturing industries and multinational enterprises in China. The comprehensive efficiency index of equipment has become an important standard to measure the production efficiency of enterprises, and it is also one of the important means to implement TPM. The first application of OEE can be traced back to 1960, which is used as the key measurement value of TPM. TPM is a factory improvement method, which mobilizes employees' autonomy by mobilizing their sense of ownership, thus improving the manufacturing process level continuously and rapidly.
