We consider a complex recyclable waste collection problem that extends the class of vehicle routing problems with intermediate facilities by integrating a heterogeneous fixed fleet and a flexible assignment of destination depots. Several additional side constraints, such as a mandated break period contingent on tour start time, multiple vehicle capacities, and site dependencies are...

We propose a new aspect of mobility that combines in a same journey and in real time a carpooling service and a traditional multi-modal transportation. This mix allows to improve and complete both services. The main idea of our approach is based on the traditional multi-modal path, in which we try to sequentially substitute some subpaths of traditional multi-modal transportation to...

Demand forecast is a critical determinant of order quantity under newsvendor problem (NVP) framework and warrants major revision in the event of changing circumstances or happening of some unforeseen events having potential to alter the demand. Retailers of single period products such as fashion apparels are required to pass their orders far ahead of selling seasons and apply...

This study aims to examine the impact of an Integrated Financial System (ERP system) implementation on accountant profiles in Swiss public administrations. ERP systems are widely researched by authors and are described as a form of change driver. Conversely, the types of changes and, more specifically, the consequences on accountants’ profiles are not studied and are therefore the...

Interstitial lung diseases (ILD) involve several abnormal imaging patterns observed in computed tomography (CT) images. Accurate classification of these patterns plays a significant role in precise clinical decision making of the extent and nature of the diseases. Therefore it is important for developing automated pulmonary computer-aided detection (CAD) systems. Conventionally, this...

Capacity utilization is a major concern for restaurants as they seek to maximize revenues, because unoccupied restaurant tables, which essentially represent lost revenue, cannot be stored for use on other days. A new type of social commerce, namely group-buying platforms has achieved great success in attracting new consumers and increasing store traffic. This study attempts to...

In the context of economic turmoil, firms in the creative industries (CIs) must make fast decisions as to when to break through with innovations. This paper discusses nontechnological, organizational innovation of early-adopters, first movers and early followers in order to overcome persistent economic decline, and the implication of different strategies for innovation success. The...

This paper examines the role of hotels in Markowitz’s mixed assets portfolios. First, we compare the efficient frontiers of pure-play asset portfolios, namely S&P indices, and hotels (REITs, REOCs and NCREIF). Further, we break the hotel stocks into asset-heavy versus asset-light categories. We find that mixing pure-play hotel assets into the portfolio pushes the frontier...
