OR AND operators in set analysis

[#1]

Hi All,

help me in this set analysis:

I need to consider activities with start into an interval defined by two variable either activities with start before interval with end after interval

Only

(

  {$    <

                          TIME_BEGIN = {'>$(TimeBeginZ)<$(TimeEndZ)'}

                          OR

                          {

                          TIME_END    = {'>$(TimeEndZ)'}

                          AND

                          TIME_BEGIN = {'<$(TimeBeginZ)' }

                          }

           >

    }    

  TIME_END-TIME_BEGIN

)

How can I insert the second set?

Only

(

{$    <

            TIME_BEGIN = {'>$(TimeBeginZ)<$(TimeEndZ)'} 

         >

  }   + 

{$    <

            TIME_END     = {'>$(TimeEndZ)'},

            TIME_BEGIN = {'<$(TimeBeginZ)' }

         >

  }    

  TIME_END-TIME_BEGIN

)

Thanks in advance

Try like:

Only

(

{$    <

            TIME_BEGIN = {'>$(TimeBeginZ)<$(TimeEndZ)'}

        >

    +

   <  TIME_END    = {'>$(TimeEndZ)'}>

            *

      <     TIME_BEGIN = {'<$(TimeBeginZ)' } >

  }

  TIME_END-TIME_BEGIN

)

Edit: Corrected the brackets.

Hi Corrado,

Only

        >

    +

   <  TIME_END    = {'>$(TimeEndZ)'}, TIME_BEGIN = {'<$(TimeBeginZ)' } >

  }
