ICCSA 2018 was a successful event in the International Conferences on tational Science and Its Applications (ICCSA) conference series, previously held inTrieste, Italy (2017), Beijing, China (2016), Banff, Canada (2015), Guimaraes, Portugal(2014), Ho Chi Minh City, Vietnam (2013), Salvador, Brazil (2012), Santander, Spain(2011), Fukuoka, Japan (2010), Suwon, South Korea (2009), Perugia, Italy (2008),Kuala Lumpur, Malaysia (2007), Glasgow, UK (2006), Singapore (2005), Assisi, Italy(2004), Montreal, Canada (2003), and (as ICCS) Amsterdam, The Netherlands (2002)and San Francisco, USA (2001)

Compu-Computational science is a main pillar of most current research and industrial andcommercial activities and it plays a unique role in exploiting ICT innovative tech-nologies The ICCSA conference series has been providing a venue to researchers andindustry practitioners to discuss new ideas, to share complex problems and theirsolutions, and to shape new trends in computational science

Apart from the general tracks, ICCSA 2018 also included 33 international shops, in various areas of computational sciences, ranging from computational science

and virtual reality The program also featured three keynote speeches

The success of the ICCSA conference series, in general, and ICCSA 2018, inparticular, is due to the support of many people: authors, presenters, participants,keynote speakers, session chairs, Organizing Committee members, student volunteers,Program Committee members, International Advisory Committee members, Interna-tional Liaison chairs, and people in other various roles We would like to thank themall

We would also like to thank Springer for their continuous support in publishing theICCSA conference proceedings and for sponsoring some of the paper awards

Welcome to Melbourne

Melbourne is the state capital of Victoria, and is currently the second most populouscity in Australia, behind Sydney There are lots of things to do and experience while inMelbourne Here is an incomplete list:

– Visit and experience Melbourne’s best coffee shops

– Discover Melbourne’s hidden laneways and rooftops

– Walk along the Yarra River

– Eat your favourite food (Chinese, Vietnamese, Malaysian, Italian, Greek, anything,

… you name it)

– Buy souvenirs at the Queen Victoria Market

– Go up to the Eureka, the tallest building in Melbourne

– Visit Melbourne’s museums

– Walk and enjoy Melbourne’s gardens and parks

– Visit the heart-shape lake, Albert Park Lake, the home of the F1 Grand Prix– Simply walk in the city to enjoy Melbourne experience

– Try Melbourne’s gelato ice cream

Basically, it is easy to live in and to explore Melbourne, and I do hope that you willhave time to explore the city of Melbourne

The venue of ICCSA 2018 was in Monash University Monash University is amember of Go8, which is considered the top eight universities in Australia MonashUniversity has a number of campuses and centers The two main campuses in Mel-

is only 12 minutes away from Melbourne CBD by train

The Faculty of Information Technology is one of the ten faculties at MonashUniversity The faculty has more than 100 full-time academic staff (equivalent to therank of Assistant Professor, Associate Professor, and Professor)

I do hope that you will enjoy not only the conference, but also Melbourne

The case study is represented by one of the most prestigious public real-estate assets

The building, whose origins seem to date back to the fourteenth century, has a

All the rooms are covered with layers of plaster which do not leave a glimpse of the

The general state of conservation is not in negative condition, since there are nostructural movements or lesions of any kind However, in order to make the buildingusable again, some interventions aimed at restoring degradation caused by the use ofthe structure and the natural deterioration of the elements are still necessary One of thefirst problems concerns rising damp, typical of the first levels of historic buildings, due

3 Methodology

Due to the non-use and advancing of the physical degradation of the structures, todaythe building object of study only represents a cost for the Municipal Administration Inthe hypothesis of its valorization it can instead represent an opportunity for economicdevelopment of considerable importance if and only if a careful evaluation of feasibility

is made on the choice of the functional alternative that pursues the economic highestand best use for the asset, in the context of possible uses permitted by legal norms

To reach the goal, we resorted to the Highest and Best Use Analysis (HBU), apreliminary assessment technique that allows to identify the economic highest and bestuse among the possible uses, technically, physically and legally possible for a asset,considering its peculiarities, the needs of the context and of the owners of the building.The process of this analysis is therefore based on the conformity of some decision-

In order to support the design of re-use alternatives, were taken into considerationthe main categories of stakeholders with different levels of interest/power, for each of

the functional alternative able to produce higher income; this is possible starting from

forecasting tools that lead to formulate an economic judgment on the feasibility of the

Starting from the current physical state of the asset, to assess the various functional

the alternatives in the hypothesis of concession to a private investor entity, which

for twelve years, while the Administration would collect for the duration of the

second year

Through the development of the DCFA it was therefore possible to determine the

indicators such as the Net Present Value (NPV) calculated as the sum of the discounted

annual cashflows with an appropriate rate discounting, and the Internal Rate of Return(IRR) The IRR is that interest rate (or discount) determined by the return on theinvested capital In other words, the IRR is the rate that cancels the VAN, or that rate

In the calculation of the NPV, the reference time frame considered is nine years, asrequired by the law on leases for hotel activities pursuant to law no 392/1978 Inaddition, a sensitivity analysis was carried out considering two discount rates at 5%and 8%

Moreover, the Break-even Analysis allowed, instead to know the break-even pointbetween costs and revenues and therefore to quantify the period of time necessary for

Finally, it was assumed that the Administration will divest the use of the propertyfor consideration to a hypothetical private manager, that will manage the activitiesplanned for the structure and will bear not only of the operating costs resulting from theimplementation of the activities, but also of the costs related to the restructuring,ordinary maintenance, annual provisions for the extraordinary maintenance as well asthe purchase of equipment and furnishings useful for carrying out the activities

This scenario involves the renewal of the current accommodation structure, whichcurrently features 11 rooms, 25 beds, a restaurant with 110 seats, a pizzeria, and a

According to the HBU procedure, the scenario have been evaluated in order toverify:

– Technical Feasibility: the planned interventions are all compatible and consistentwith the historical structure, indeed, they are aimed at improving the conditions ofusability

– Juridical Feasibility: the planned interventions and the envisaged functions of thebuilding is legally compliant Since no variations have been proposed from thepoint of view of volume and structural, the building responds to the regulations onseismic safety in force Furthermore, despite being a historic building, is not subject

to monumental bonds pursuant to Legislative Decree 22 January 2004, n 42, but as

a historical building built for more than seventy years, it is subjected to the
