The objective of this study was to propose a multi-criteria optimization and decision-making technique to solve food engineering problems. This technique was demonstrated using experimental data obtained on osmotic dehydration of carrot cubes in a sodium chloride solution. The Aggregating Functions Approach, the Adaptive Random Search Algorithm, and the Penalty Functions Approach were used in this study to compute the initial set of non-dominated or Pareto-optimal solutions. Multiple non-linear regression analysis was performed on a set of experimental data in order to obtain particular multi-objective functions (responses), namely water loss, solute gain, rehydration ratio, three different colour criteria of rehydrated product, and sensory evaluation (organoleptic quality). Two multi-criteria decision-making approaches, the Analytic Hierarchy Process (AHP) and the Tabular Method (TM), were used simultaneously to choose the best alternative among the set of non-dominated solutions. The multi-criteria optimization and decision-making technique proposed in this study can facilitate the assessment of criteria weights, giving rise to a fairer, more consistent, and adequate final compromised solution or food process. This technique can be useful to food scientists in research and education, as well as to engineers involved in the improvement of a variety of food engineering processes.

The given mathematical model of thermological processes on the clayey ground of the road construction where the embankment of the roadbed turns into excavation allows using it effectively choosing the technological schemes and operations.

In the design of horizontal curves, the speed is set by the criterion of sustainability train. To determine the reliability of calculation methods and the effectiveness of interventions, arranged in these areas conducted field observations of the modes of movement of vehicles on curves. As a result of of data research in the field conditions established that at application of of this approach to designing of of transient curves with the device Superelevation the calculated speed of movement of on the given sites approached to normative for the data of categories of roads.

The article describes a method of dynamic analysis of pavement bodies of timber road Ukhta – Troitsky-Pechorsk, a forecast of full sinkage and consolidation time of the subsoil. Reinforcing gravel with geogrids increases the overall (equivalent) elastic modulus of structure for 6…15 %, reduces the magnitude of the tangential stress in the layer, underlying the geogrid by 25…80 %, increases the modulus of defor-mation with significant precipitation more than in 2 times.

In the article the methods of artificial grouting in the construction and reconstruction of forest roads on weak based using electrochemical treatment, soils, thereby squeezing the labor intensity and increasing the degree of mechanization of work. The method of electrochemical treatment of the soil is to use the effect of electro and spryagatelnyehim processes.
