In this article, the method of selecting the number and carrying capacity of rolling stock on the technological routes of the transport and production system of recycling technological waste of a metallurgical enterprise has been improved. The main features of the organization of the transportation of metallurgical slag at domestic enterprises are given, among which it is advisable to highlight the following: a limited number of types of rolling stock on the routes, a short distance of cargo transportation (compared to the transportation of other types of cargo), continuous technological processes, which lead to a 24-hour working mode with minimal interruptions for lunch and staff changes, fairly stable daily volume of transportation, etc. The selection of the number and carrying capacity of rolling stock as one of the main means of managing transport and production systems is substantiated. It is proposed to choose as a criterion for the effectiveness of the system's functioning - the minimum time for the transport to be idle while waiting for the performance of cargo operations. For this, the traditional formulas for calculating the required number of rolling stock on the transport route were transformed. Taking into account the above-mentioned features of the functioning of the transport and production system, the expressions for determining the necessary number of rolling stock were obtained, taking into account the criterion - the minimum time for the transport to be idle while waiting for the performance of cargo operations. This made it possible to carry out calculations with the simultaneous use of vehicles of different load capacities. The results of the calculations made it possible to determine the most rational option for using rolling stock of a certain carrying capacity. In order to assess the possible impact of unevenness, traffic schedules of vehicles on the transportation route were constructed. A statistical analysis of the duration of the load was carried out, which made it possible to determine that a decrease in the duration of idle time is observed in 40% of vehicle turnovers, of which only 3% of cases can lead to violations of the rhythmicity of the schedule. Thus, establishing a rational length of downtime of dump trucks while waiting for unloading is an important element of the organization of the transportation process.

“…In order to calculate the fitness of an individual, each carrier bids on an allocation. To start with and in line with the vast majority of the literature [3,4,6,11,12], we assume truthful bidding. Given an allocation α, each carrier a ∈ A calculates its bid price b a (α).…”

“…In an auction the requests are tendered, the carriers submit bids on the requests, and the auctioneer decides which bids win the auction. Individual carriers are responsible for their routing and valuation decisions [3,4,6,11,12] which appears to be a welcomed feature by many coalitions.…”

Terms of use: Documents in Impact of Non-truthful Bidding on Transport Coalition Profits Jonathan Jacob and Tobias BuerAbstract A coalition of freight carriers is considered which has to decide how to allocate a pool of transport requests among its members. The literature is aware of a number of solution approaches which usually assume truthful behavior of the freight carriers. However, the used negotiation protocols are mostly not proven to enforce truthful behavior. This paper gives some insights into the impact of non-truthful behavior via computational experiments. We solve the collaborative problem via a genetic algorithm (GA) which is operated by an auctioneer. The GA's individuals are allocations of requests to carriers. To calculate the fitness of an individual, the carriers bid on the allocations. Bidding below a carrier's true valuation could ceteris paribus increase its profits. However, understated valuations can influence the search process negatively, in particular when a favoured allocation is dismissed wrongly. It is shown via computational experiments that for six tested instances, bidding non-truthfully is individually, but not collectively, rational and results in a kind of prisoner's dilemma.
