Work Package 2. Fundamental research for development of scientific methods for tactical design and management of sustainable SCs for dairy products production taking into account environmental, economic and social impacts in the context of certain and uncertain data.

Research tasks:

T-2.1. Development of a mathematical method for analysis, tactical design and management of sustainable SCs for compatible production of various dairy products in order to maximize profit from production while meeting environmental, economic and social criteria.

Research goal. Creating mathematical method for analysis, tactical design and management of SCs for compatible production of various dairy products in order to achieve a maximum production portfolio taking into account their environmental, economic and social impacts.

Description: 1) Creating mathematical models of the economic, environmental and social impact of SCs in the context of certain data; 2) Formulation of appropriate environmental, economic and social optimization criteria; 3) Formulation and solution of the problem for the design of an optimal production portfolio for compatible production of various dairy products on example from the dairy industry, using the software packages Mathcad and GAMS.

T-2.2. Development of a mathematical method for analysis, tactical design and management of sustainable SCs for dairy products production in different technologies to meet the requirements of all the actors in the supply chain.

Research goal. Creation of a mathematical method for analysis, tactical design and management of SCs for dairy products production in different technologies in order to meet the requirements of suppliers and end users.

Description: 1) Conducting an environmental analysis of the pollutants that can be expected along the supply chain, taking into account the environmental impact of the technologies used in the production of products; 2) Creating mathematical models of the technologies used for dairy products production in the context of certain data; 3) Creating mathematical models of the economic, environmental and social impact of SCs; 4) Formulation of appropriate economic criteria to assess all actors in the supply chain; 5) Formulation and solution of a multi-objective problem for design an optimal sustainable production portfolio while simultaneously meeting the requirements of suppliers and end-users on an example from the dairy industry by using the software packages Mathcad and GAMS.

T-2.3. Development of a mathematical method for analysis, tactical design and management of sustainable SCs for dairy products production in order to maximize the profits from the production, taking into account their environmental, economic and social impacts in the context of uncertain data.
