Discrete Gompertz equation and model selection between Gompertz and logistic models
International Journal of Forecasting, 2021A discrete Gompertz model and model selection between the Gompertz and logistic models are proposed. The proposed method utilizes the difference between the regression equations for the proposed and the discrete logistic models. The difference is whether

The Effects of Sample Size and Logistic Models on Item Parameter Estimation
Proceedings of the 2nd International Conference on Education, ICE 2019, 27-28 September 2019, Universitas Muhammadiyah Purworejo, Indonesia, 2020This research aims to ascertain: (1) the effects of sample size (N) to determine item parameters; (2) the effects of logistic models (1PL, 2PL, and 3PL) on item parameter estimation.

Fractional logistic models in the frame of fractional operators generated by conformable derivatives
Chaos, Solitons & Fractals, 2019In this article, we study different types of fractional-order logistic models in the frame of Caputo type fractional operators generated by conformable derivatives (Caputo CFDs).

In a logistics system the number of possible applications of qualitative and quantitative modelling efforts is practically infinite. The situations or problems which can be analysed range from micro operations (e.g., analysing alternative order picking systems) to macro planning issues (e.g., determining the number and location of warehouses to be ...

This paper propose an innovative simulation model based on web technologies devoted to analyze environmental impact of the whole supply chain. The authors developed a whole framework for collecting data from different users including good producers, logistics operators and retailers by a web questionnaire; this service is automatically integrated with ...

SUMMARY The multivariate logistic transform is a reparameterisation of cell probabilities in terms of marginal logistic contrasts. It is known that an arbitrary set of logistic contrasts may not correspond to a valid joint distribution. In this paper we present an efficient algorithm for detecting whether or not the inverse transform exists, and for ...

Urban freight systems are experiencing many problems due to higher levels of service and lower costs being demanded by shippers, with carriers having to operate in increasingly congested road conditions. Trucks operating in urban areas produce many negative impacts for society in terms of emissions, crashes, noise, and vibration.
