# A mathematical estimator for the design of large plants

This case protagonist is one of the most important world players in the construction of large chemical and petrochemical plants. Together we have developed an estimator, based on mathematical models, able to estimate the typologies and the quantities of materials necessary for a new project.

- Description and benefits

Prior to our work, the company realized the estimates relying **exclusively** on the experience of its technicians, with a great use of **time** and **resources**. Supported by the availability of historical data and the in-depth knowledge of the company's experts, we developed an algorithm that outputs a preliminary estimate of the materials to **be provided** to the design engineers.

Our algorithm enables the company to calculate the total quantities of materials **required** for the project.

Moreover, it can provide detailed indications of the different **parts** and **types** of material that compose the **overall plant**.

###### Quick estimates

Decrease in processing time (from days and weeks to hours)

###### More accurate planning

Quantities and types of materials needed for the project can be known in advance

###### A more accurate estimate

There is less chance that an estimate will deviate too much from the actual cost

##### Deepening case study

Augmented human: the encounter between mathematical models and human experience

What we have realized for this customer is a set of **models that estimates** the various types of materials (pipes, valves, flanges, etc.). Before constructing a final comprehensive output, our software provides the possibility of **verifying** the quantities step by step and making any corrections, based on the operators own **experience**, to obtain an increasingly precise result. The user can also provide **guidance to the model** on expected input-output relationships to lead the estimation process in the most unexplored contexts. These results are then **reworked** by our models to arrive at the final overall estimate.
