1. System selection and introduction:<\/strong>
\nThe system used for the first assignment was a public playground for children consisting of
\nground, swing, slide and see-saw. For the assignment in hand a combination of the ground and
\nthe swing were selected, they were connected considering that the usage of the swing affects the
\ndeterioration of the ground depending on the used material.<\/p>\n

2. Parameter definition for the calculation of quantities:<\/strong>
\nThe main parameter is the number of swing seats N. Which is used to calculate the dimensions of
\nthe profiles used for the construction of the swing. The second parameter the area of the
\nplayground A which is used to calculate the quantities for the selected ground material.
\nTwo design options for construction of the swing are considered. The first is a steel construction
\nwhile the second is a wooden construction.<\/p>\n

 <\/p>\n

 <\/p>\n

The Swing consists of mainly posts (vertical) a bar (horizontal). the number of posts is calculated
\nconsidering that every two swing seats need an additional post, therefore I used the equation:
\nNrPo = 1 + ceil(N\/2). The necessary length of the bar is calculated with the equation: L = N*1,10
\n[m].<\/p>\n

3. Design options:<\/strong>
\nCombining our possible design variations we get the following options to asses and compare:<\/p>\n

Design Option Swing Material Ground Material
\nOption 1 Steel Rubber
\nOption 2 Steel Sand
\nOption 3 Steel Artificial grass
\nOption 4 Wood Rubber
\nOption 5 Wood Sand
\nOption 6 Wood Artificial grass<\/p>\n

4. Goal and scope definition:<\/strong><\/p>\n

The main goal of the life cycle assessment is to evaluate the amount of produced industrial waste.
\nThe scope and system boundary are represented in the following figure. The industrial waste<\/p>\n

\"rt\"<\/a>
\n<\/a><\/p>\n

could be produced all along the way from the extraction of raw materials to maintenance actions.
\nThat is why the system boundary must include more than just the construction and maintenance
\nof the system.
\nThe necessary interventions that were considered in the assessment are listed below:
\n– RuRe: rubber replacement.
\n– P: Paint.
\n– RP: Repositioning.
\n– SaRe: Sand refill.<\/p>\n

– GrRe: Grass replacement.<\/p>\n

– JI: Joints inspection of the wooden construction.
\nThe time lines with the necessary interventions were created for each design option. The following
\nfigure is the timeline of design option 5.<\/p>\n

 <\/p>\n

5. Life cycle inventory:<\/strong>
\nThe amounts for each material is calculated using the mentioned equations. A life cycle inventory
\nhas been established for each material and it includes the information about produced waste up
\nto the point of construction. In addition, the quantities needed for each intervention during the life
\ncycle of the subsystem. All amounts are provided in cubic meter. The values are imaginary and in
\nreal life need to come from an authentic source of course. These values are stored in a csv file
\nthat is also uploaded with the submission.<\/p>\n

 <\/p>\n

6. Life cycle assessment:<\/strong>
\nBased on the created timeline we get the amounts of intervention needed for each design option.
\nThe total volume of industrial waste is calculated using the following equations using the following
\nequations:
\nTotal waste = production waste + maintenance waste. Maintenance waste = maintenance waste *
\nquantity * number interventions.
\nProduction waste = production waste * quantity.<\/p>\n
