**Abstract.** Technical Committee 7 of IFIP was created first to establish a bridge between group of mathematicians and engineers working in modeling and optimization in the east and west countries. With changing world it became an important scientific group stimulating research in modeling and optimization. This note is trying to summarize activities of the Technical Committee over the last 50 (and more) years.

**Keywords:** optimization, modeling, systems.

# 1 Early years of TC7 and TC7 in present time

The idea to create TC7 appeared for the first time during IFIP meeting in 1967 in Rome, where A.V. Balakrishnan, J. L. Lions and M. Marchuk were thinking about forming a research coalition devoted to Modeling and Optimization. Officially IFIP TC7 was founded in 1972 by A.V. Balakrishnan, J. L. Lions and M. Marchuk.

The aims of this Technical Committee were formulated as follows (and there are still actual):

* To provide an international clearing house for computational as well as related theoretical aspects of optimization problems in diverse areas and to share computing experience gained on specific applications,
* To promote the development of necessary high-level theory to meet the needs of complex optimization problems and establish cooperation with the international Mathematical Union and similar organizations,

* To foster interdisciplinary activity on optimization problems spanning the various areas such as Economics (including Business Administration and Management), Biomedicine, Meteorology etc., in cooperation with associated international bodies.

Generally at that time it was important to create a research bridge between West and East. IFIP TC7 for a long time played this role. Geopolitical changes in Europe improved channels of scientific cooperation and stimulated further development of TC7.

All members of TC7, in particular chairmen had strong impact on its activities.

The list of chairmen of IFIP TC7 looks as follows:

A.V. Balakrishnan, Los Angeles, US 1972-1979

J. Stoer, Würzburg, D 1979-1985

## 2 Scope of the activities of TC7 and working groups

Generally speaking the scope of TC7 is two-fold: to foster the theoretical foundation for problems of the TC's concern and, based thereon, to develop or improve corresponding solution methods and their implementations. This broad scope of the TC7
is studied by a number of Working Groups which are involved both in the progress of
theoretical research and in the growth of practical needs.

The scope of TC7 consists in computational aspects of optimization problems aris-
ing in such areas as Aerospace, Biomedicine, Economics, Meteorology, and Public
Services (Health, Environment, Police, Fire, Transportation, etc.).

Some specific examples are:

* on-line and off-line computational techniques in modeling and control of dynamic systems;

* trajectory analysis and computation;

* optimization of decentralized systems (macro-economic systems) and systems with multicriteria;

* optimization of resource allocation in urban systems;

* optimization of pollution-control systems;

* optimization of man-machine systems;

* optimization of power systems operation;

* risk management in particular in mathematical finance and insurance;

* development of machine learning techniques;

* optimization and control under uncertainty.

There are 8 Working Groups being active within TC7, which we list below (in brackets we write year of foundation and the name of the first chair at foundation) with named chairs of them:

WG7.1 Modeling and Simulation (1972, W.A. Karplus, USA), temporarily sus-
pendesince 2018

3 General Conferences

One of the main activities of TC7 are general conferences, which in fact started be-
fore creation of TC7. The conferences had different names but starting from 1981 it
was fixed to System Modeling and Optimization. TC7 general conferences played an
important role in research activities. They gathered usually a number of leading spe-
cialists. Plenary lectures were delivered by mathematicians and engineers working in
theoretical and practical aspects of various applications.

ence) are organized every two years.

There was no proceeding of the 24th Conference held in Buenos Aires. Because of the swine flue epidemics the usual attendance of the conference from Europe and North America was under represented and we had relatively small number of participants (about 119). The 28th Conference was primary scheduled in Ankara 2017 but due to unstable political situation it was cancelled and moved in 2018 to Essen. Due to coronavirus pandemic the 29th IFIP Conference in Quito has been postponed to 2021 and will be held online. The 30th Conference will be on July 4th-8th 2022 in Warsaw, to continue general conferences every two years in average.

## 4 TC7 future activities

Modeling and optimization seems to be still important in various applications. Recent interest in machine learning techniques in particular in reinforcement learning and quality learning stimulate applicability of the research works of TC7.

Another area is big data, large scale problems, the problem to find adequate methods as well as sufficiently efficient implementations. Together with an increase of the power of computers we need to develop suitable mathematical tools to handle such problems.

Modeling of coronavirus pandemic is another hot problem in the area of interest of TC7. Consequently there are a lot of to be done in modeling and optimization and therefore we are looking optimistically to the near future.
