Upper and lower bounds for the vehicle-routing problem with private fleet and common carrier
2019
Abstract The vehicle-routing problem with private fleet and common carrier (VRPPC) extends the capacitated VRP by considering the option of outsourcing customers to subcontractors at a customer-dependent cost instead of serving them with the private fleet. The VRPPC has important applications in small package shipping and manufacturing, but despite its relevance, no exact solution approach has been introduced so far. We propose a branch-price-and-cut algorithm that is able to solve small to medium-sized instances and provides tight lower bounds for larger instances from the literature. In addition, we develop a large neighborhood search that shows a decent solution quality and competitive r…
Efecto Bullwhip y restricciones de capacidad productiva en las cadenas colaborativas
2008
El objetivo del presente artículo es profundizar en el análisis de Evans y Naim (1) sobre la relación entre la capacidad de limitada producción y el efecto bullwhip, y actualizarlo en función de las recientes configuraciones de cadenas de suministro colaborativas. Se analizan tres cadenas de suministro con capacidad de producción limitada: la misma cadena de suministro tradicional estudiada por Evans y Naim (1), una cadena EPOS (Exchange Point of Sales) y una cadena sincronizada. Se adopta un sistema de métricas para evaluar los beneficios de los nodos de la cadena medidos en términos de estabilidad de la orden de pedido, estabilidad de los inventarios, y robustez del sistema, y en términos…

The ‘gig economy’: employee, self-employed or the need for a special employment regulation?
2017
The digital era has changed employment relationships dramatically, causing a considerable degree of legal uncertainty as to which rules apply in cyberspace. Technology is transforming business organisation in a way that makes employees – as subordinate workers – less necessary. New types of companies, based on the ‘on-demand economy’ or so-called ‘sharing economy’ and dedicated to connecting customers directly with individual service providers, are emerging. These companies conduct their entire core business through workers that they classify as self-employed. In this context, employment law is facing its greatest challenge, as it has to deal with a very different reality to the one existi…
The Market’s Maturity for Public Procurement of Circular Furniture: A Study from Latvia
2021
Public procurement plays an important role in the market by making up 14% of the Gross Domestic Product in the European Union, therefore it is seen as an important instrument to promote such products and services that better meet society’s demands, for example, sustainability. Starting from 2015, circularity is an important aspect of sustainability. Furniture is among the product groups with a significant impact on the material footprint, therefore approaches to increase material efficiency and circularity are of high value. With this research, the authors investigate the market’s maturity, i.e. the readiness of suppliers to offer circular furniture and services, as well as the readiness o…

How do startups develop internet-of-things systems : a multiple exploratory case study
2019
Internet-of-Things applications are not only the new opportunity for digital businesses but also a major driving force for the modification and creation of software systems in all industries and businesses. Compared to other types of software-intensive products, the development of Internet-of-Things applications lacks a systematic approach and guidelines. This paper aims at understanding the methodological commonalities among startups who are developing Internet-of-Things products. Using the SEMAT Essence framework, we captured common team compositions, common types of Minimum Viable Products and common way of working in early stage Internet-of-Things startups. We found that startups includ…

Reintegration Failure and Outsourcing Upside: Organisation of Public Transport in Norway
2014
AbstractAfter two decades of public sector outsourcing, debates for reintegration of services back into the public sector have emerged. However, so far outsourcing remains prevalent and reintegration is sparsely utilised. An in-depth analysis of the reorganisation of public transport in a Norwegian county, Sor-Trondelag, provides three key reasons as to why there is an ‘outsourcing upside’. Firstly, existing structures limit available alternatives for legislators, thereby making reintegration of public services back into public hands difficult. Secondly, under certain conditions competitive tendering may enhance political steering and thus make outsourcing politically desirable. Thirdly, th…
